I am getting ready to buy a new car that is built using a small metric frame,a friend of mine has the same type of car and said that the metric spindles bend very easy and they dont have the best front end geometry,so I am wondering if I could take my pinto spindles off the old car and put them on the new car,and if so,what all I would have to do to make it work.thanks

You can. The only problem I had was the need to trim around the lower ball joint for clearance on the rotors. I use Granada rotors, (took them off my DW with Pinto and Granada). I just switched them over last night BTW, I agree with the Pinto spindles...5 years on the same ones and no bends...I hope I didn't just jenks myself.

Absolutely correct I run mine this way as well.

Just curious though is the T-bird/torino spindle the same as the Pinto/granada? Only you'd flip them to the oppsoite side to make them a front steer instead of a rear steer? I can't tell a difference, but I was wondering if there may be some caster built into the spindle, and I'm worried it may bind or cause some weird geometry.

the t-bird spindle is different than the pinto spindle. you don't want to run a rear steer spindle on a front steer car by flipping the spindles. it's the ackerman that will be way off not the caster.

the pinto spindle is shorter than the granada spindle and shorter than the metric spindle too. the steering arm on the pinto is also shorter. i think the shorter steering arm should be quicker but require more effort. maybe the longer ball joints could be a benefit in the swap as far as the height of the spindles go.

I use the lower that is 1 inch taller to raise it.

Perhaps I have the wrong spindles in mind, but I've held two of these next to each other and couldn't tell the difference. The length from the lower ball-joint to the tie-rod end was the same on both, therefore I can't see where ackerman would be effected. I slot the tie rod attachment and use different slugs to adjust ackerman anyhow so that I'm not worried about.

Perhaps I am thinking of the wrong spindles though. I also have a T-bird based mod and I thought it used Granada spindles, are they the same as a pinto spindle?

I reamed the ball joints and used large ***** in ball joints for a Dodge 1-ton. That's the way this frame of mine was built. It's a Dave Bice car from Indiana. Works great on dirt and asphalt.

HRT187, t-bird/torino, granada and pinto spindles are all different. ackerman has nothing to do with the length of the steering arm. ackerman is built into the spindle with the placement of the steering arm relative to the placement of the lower ball joint. i don't think an offset slug could change the ackerman enough to use a rear steer spindle on a front steer car. i'm not absolutely certain of this as i've never tried it.

pinto/mustang2 spindles are the only one of the three that are front steer.

crown victoria spindles are front steer, that might be another option.....

if you do use a rear steer spindle on a front steer setup without correcting the ackerman. the steering will toe in as it is turned. normal tendency is for the wheels to toe out when the steering is turned.

I think Wayne Larson cars are using granada spindles on there frontsteer cars, or at least they did a year ago.

that would put the caliper on the front side of the rotor. is that a good thing?

ok, that explains my questions about which ford spindles are which. But I could have sworn a T-bird spindle was the same as a granada spindle.... not so eh? I'm talking about the T-bird frame that had the tension link (hockey-stick, golf-club) LCA.

As for changing ackerman, if you shorten the steering arm but translate it the same distance with the tie rod how are you not going to change ackerman? The shorter the arm the more the spindle will turn. At least that's what my turning plates tell me. And an interesting paper I read which was someone's BSME senior thesis from Kettering University.

Now, if the the tie rods make a strange angle with the drag link that is where you may come up with some ackerman as well.

Thanks for clearing up my spindle confusion.

Does it matter? I thought it was just a packaging thing? Couldn't you make custome brackets? I think my car with pinto spindles has homemade brackets.
