I just bought a buick regal that I am going to build as a next season hobby stock and I was wanting to replace the small GM Rear-End with a 9" Ford and I need some advice.

I know the lower trailing arm brackets and all will have to be welded on the 9" rear from the small GM.

My question is what would have to be done to get the upper control arms hooked to the 9"Ford is there a 9" Ford that comes with these brackets made on the upper top of the housing or would I have to build some and weld them on?

Thank you for any help.
Steve.

You could just buy the housing with mounts already welded on it, narrowed up or just the mounts from www.quickperformance.com

Thank you Customperformance.

I already have several 9" Ford rear ends and I am a welder by trade I think I will cut the lower trailing arm brackets of the small GM and build some upper bushing brackets.

Some of my friends have done it but there are areas of their cars they will not let me look at lol.

Thank you for the info.
Steve.

thats a new set up to me there 05 i like it makes it adjustable to bad we couldn't run something like that but anyway i'd suggest taking it to a local chassis builder that has a jig and have it set up right with the proper angles and stuff we have a jig and like you use the stock mounts for the lowers and on the top we use rectangle tube and weld a piece of heavy duty round tube to hold the bushing in and weld that on top of the housing.

Steve,Speedway Motors sells a bracket kit to put a 9" ford in a metric chassis, REAL PRICEY $179.95! Looking at the picture a clever fella could figure out how to make them I bet... loojack

Thank you guy`s for the information.

No our rules will not allow floater rear-ends.I have a Speedway motors book but cant seem to find the trailing arm bracket kit and the book is a 2002 50th anniversary edition.

Thanks again Steve.

in order to be competitive you first need to know that you must put some pitch in the rear end and the best way to do the top trailing arms is to weld a piece of square tubbing on the top and then put some kind of spacer like you have on you alternator bracket the bushing that is there that type but you need to really know how much pitch to have that way you will get enough fprward bite out of the car if it was me i would have the top trailing arms jigged for this purpose even though you are a welder you need to really have it done that way.
if you have any further questions you can e-mail me at

go to the local salvage yard, find an old Elderado or tornado. the ones with the big engines and the 5x5 bolt circle. like 76-80 or so. these have a solid axle, just no pumpkin in the middle. cut the top mounts off they are alot taller than you will need, so you dont have to worry about cutting them very close to the tubes. the lowers are easy, you can use your old ones from the same rear your taking out. The Gm tubes are smaller OD than the Ford you'll be putting in. So when you carefully cut with the torch, what your left with will fit perfectly on your 9" hosing. be sure to add you pinion angle before welding. The good thing with the ford rears are they are taller on the pumpkin than the stock housing, and with some creative cutting, of those tall mounts you can get all the arm angle you need while maintaing the stock upper arms.
the enclosed pics are of some home made upper mounts(not the elderado mounts) and some oem(sort of) lowers.
Ill find a pic of the elderado mounts.

Thank you Widebody the pictures really helped me out.I think what I am going to do is get the car up on 4 jack stands level and then position the rear-end up under the car and get the rear-end pinion angle where I want it and hook the lower trailing arms up first by tack welding the brackets and then making the upper control arm brackets out of some square tubing that has a piece of pipe that runs through the square tubing that the upper bushings will press into.

Again thank`s a bunch.
Steve.
