How do you put this on the rear axle? Mine has the brake caliper mount welded on the tube so you can't slide anything past that. Does it come apart in halves or what?

This is the item I am refering to at this link; http://www.randys-racemart.com/leflformole.html

Thanks

You will have to cut the brake mount off, and slide the floater bracket on, then when you mount the brake bracket back on, You will need to get a clamp on one and after clamping it on, drill and tap throught the bracket and right throught the axle tube and put a bolt in it, 1/2" bolt

Well, I want it to be able to act as a floater sometimes on a slick track, but I was hoping it was a two piece design so I didn't have to undo any welding...****!

Southwest Speed makes a nice 2-piece design.

If you are going to float the leaf on right side, you should think about floating the brake also. Cut off your welded mount and put a brake floater on it.
Racemart has a brake floater bracket available also with the leaf floater.
Actually we float the brake on RR on the
FR-1 cars.

Sounds like a great idea, but I can't seem to find that floater/leaf mount/brake bracket at Racemart. I will keep looking, but if you find a part number I would appreciate it if you would put it on here.

Thanks

look under his chassis parts & gauges page, just click on the link on the left side of his screen,
Steel small GM brake floater is how its titled for brake floater, its at bottom of page
the leaf mount is on there also, available in a weld on or a bolt on bracket.
Leaf floater is located just beside the leaf bracket.

That our just give Randy a call, ask for Randy or Art. They will fix you right up.

I read your other article also, if possible i would recommend going to the chrysler springs if you can.
That will help reduce your wheel base. 113 is pretty long.

Great! You read my mind on a question I had about the wheelbase. I wanted to go with the Chrysler springs and now I will. If I have to cut the wheel openings a bit more at the front then that will be no problem. It looks like that would give me more room for the fuel cell too.

One more thing, I have read different approches to this and that is the angle of the mounting ends on the leafs. Should they have a pretty good difference between levels from front to back or should the mounting points be slightly different with a slight rise to the back mounting point?

I really appreciate this.

yes you want the springs to tapper inwards to the front.
If i remember right AFCO's web site has this information on locating spring mounts front and rear.
I'm not sure what the exact measurements are, but Randy (racemart) can give you this informaiton also.

Are you going to run a multi leaf on LR and a mono leaf RR with coil spring??
If so i would recommend Racemart's multi leaf. On the mono you can go with the afco leaf.

Thanks mod27. I am definately going with the mono rr with a coil slider and a stack on the lr. I got some rates given to me in another posting. rr mono 65# with a 150 coil and the lr with a 175#. Actually to me these seem a little stiff but I don't know if the rates on a leaf are the same as a coil. I ran a Toyota that weighed the same but only had 100 lr and 125 lr. Maybe with the extra power it needs a stiffer spring.

That is a good question about the front clip. I had someone tell me it was probably a metric, but I can't tell on my own for sure. The spindle is a GM product and is only 7 1/2 inches tall. It says GM on the rear of the spindle and it has only a 10" disc brake, but 5 on 5 bolt pattern.

The problem with that is the upper a arm never gets to angle down with the lower a arm level. I went to the junkyard and got a spindle off an older GM car with the 8 1/2" tall spindle and the 12" brake with the 5 on 5 and bigger brake caliper. Now my problem is with the drag link length. The idler arm and the steering arm are both angled in towards each other with the tires pointed straight, not real bad, but I thought they should be parallel with each other.

This car was basically given to me and I admit that I am on a real steep learning curve here. I will get it right, but as far as just looking at parts and telling what they are and if they are right is something I can't do right off without some help. I got the IMCA book from Steve Smith, but it leaves many things out that a beginner really needs. So thanks for any and all help.

Not to get you anymore confused, but its best to go with the racemart set-up stuff or the RC set up stuff. Mixing them both may not work as each builder is similar but still different also.
If you go with Racemart stuff (leaf springs), i would recommend you talk personally with Randy, he will set you up with the proper springs and weights.
Or if you go with the R/C set up, then you need to talk with Scooter Maye and he can set you up.
Both set ups are great, and i would recommend Racemart since thats what i drive. LOL


First you need to make sure what front clip you have.
second if it is a metric clip than the BIG GM stuff is not what you want. You need to stay with the metric stuff or switch to the pinto style set up.
Being new to this class i would recommend you stay with the metric stuff till you learn more about how all this works.
it sounds like you got the wrong parts for what clip it is.
if metric clip, parts you want are for 1978- up.
if chevelle clip you want 1968-1972 parts
if impala style clip its 1973-1977 stuff

Does it have tubular upper A-arms or nodular style??

It has a tubular upper arm. The upper ball joint is from a GM truck, newer model. I don't know just how to tell what front clip is on the car. Is there a way to tell from the lower A arm, from the mounting positions, from the way the chassis is made? I understand that metric means that most, if not all of the bolts are metric? The ball joints sure aren't.

It does sound like a mixture of items on the front suspension. There are many modifieds at our track, it's just that I don't know any of them right now. The guy that supplies parts for most of the stuff is in the process of moving so he is hard to track down. If there were measurements, I could find out.

Oh well I appreciate what you said about keeping with one supplier and I will do that as best as I can. I had heard from one source not to toe the rear springs in and another source said to do that. There are going to be personal preferences I know, but I am looking for a basic set up and go from there.

Thanks
Russ
