spindle swap on a 68 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

tripp · 03-22-2003, 01:53 AM

does anybody know if you can put '72 spindles on a '68 with no further modifications? I have a '72 frame with all the gear and those spindles and discs would sure be nice on my '68. I don't want to have to swap the a-arms. do i need to upgrade the ball joints and tie rods for the '72? i need help, thanks.

I beleive the tie rods and everything else are diferent sizes, do a search on the subject I know its been asked before, even though you dont want to you would save some headeach to change over everything from the 72

I'm under the impression that you can unbolt the 72 complete crossmember..........and swap it right into the 68..............

Do a search, I believe this issure has been adressed................

get new top and bottom ball joints and new tie rods for the 72 set up and you should be fine. no need to swap the A-arms or the crossmember. make sure to check all the bearings and since you got it down that far why not go ahead and resurface the rotors and get new pads.

I would be interested in what you find out about swapping 72 front spindles to a 68... I just bought a 68 that supposedly has that swap, but has some problems with steering... It seems the out side wheel on a turn, turns sharper than the inside wheel..no matter which way you turn...Right or left...
I suspect it is the tie rod ends since the part numbers are different in the parts catalogs, but am not certain..yet..

Thanks...Don

Im doing the same thing on my 69 and yes you need new upper and lower ball joints and a diff tie rod.

Hey Tripp........

Did you ever get your spindle swap to work on your 68 Chev???
I am in the process of changing the tie rod ends from 68's to 72's and wondered if I was on the right track.... What about the ball joints?? Do they have to be 72 also???

Thanks for your help in advance...

yes, the balljoints have to be 71-72 also.

tripp · 06-19-2003, 05:13 PM

i haven't been able to get to it yet. however, my front end man here in town tells me that all i need to do is swap the ball joints for 72 ball joints and change the tie rod ends for 72 models. he thinks that it may be necessary to swap out the entire steering linkage system to the 72 model to get the right setup because the steering ends that the tie rods screw onto are different sizes. there may be an aftermarket company out there that makes a tie rod adapter so the full linkage swap is not necessary. i don't know. hopefully, i'll get to it soon.

73stepside · 06-20-2003, 01:24 AM

to do the swap right you would need a master cylinder with proportion vavle for disc/drum, inner and outer tie rods, tie rod sleeves, upper and lower ball joints, center link and brake lines and hoses from a 71/72 truck. you will also need to grind down or dent the steering stops. grinding them on the spindle would be the easiest but i'm gonna dent the steering stop on the a arm of my 70 to swap in disc brakes. classic performance products does sell adaptor parts for this change over i believe.

Thanks 73 stepside....

You have told me more than I have learned in the four months since I bought my 68.... I knew there was more to it than what I had found so far.. I sure am glad there is a site like this for novices like myself...

I do have the outter tie rod ends, but it looks like I will need a few more parts to complete the job... I guess this will take a bit longer than I originally thought...

Thanks again for your input... It will finally get me on the right track...

i did a search on the board and found what the other guys had to do to put the disc's on and made a list. i still need to get most of the parts to finish mine, but i'm still sanding and painting
