73-87 upper control arms?

[leddzepp]

Just want to confirm 73-87 upper control arms will bolt right up to my 68? I’m swapping in squarebody spindles and I found a set of upper control arms that already have new ball joints installed as well as the cross shafts that have rubber bushings. They run almost the same $$ as buying ball joints alone, and I won’t have to grind rivets off of the existing ones, and I’ll get and upgrade with the rubber bushing design. Thanks in advance.

As long as you swap 1/2-ton for 1/2-ton, 3/4-ton for 3/4-ton etc. you are fine they bolt right in. Shocks bolt in also. Only mod will be routing of you brake flex hoses, some opt to reroute the hard line to the front like the 73-87 is or you can keep them as they are in the rear and get the proper length/ends flex hose. You will have to enlarge the hole on the frame bracket where the hard line and hose meet or turn the boss on the hose down if you have access to a lathe.

This is the smart way to go in my opinion. I did my 1 ton about 2 years ago and here is a link to what my experience was, not sure what your dealing with C10,20 or 30 but some of it may help you.

I (& others) don't consider the rubber bushed arms an upgrade.

The 63-72 C10 (63-89 C20/30) arms w/the threaded end caps that utilize a rubber lined steel shell allow better pivoting w/o bind vs the car style press in bushings of the 73-87 C10's.

Another point of consideration for me is that cost factor. You indicate you can get the arms loaded w/new parts for the same cost as just purchasing BJ's? Are those 'new parts' the same quality range as the BJ's you priced out?

I have to agree with you on this. That's why the C20/C30 didn't get rubber bushings on the sguarebodies. I may be wrong but I believe the C20 is the same from 63 to 87.

Thanks everyone for the input!

It’s good to confirm they will fit, in the future I may need to use the cross shafts on an aftermarket set of control arms made to use the rubber bushing design.

Since it seems there is no upgrade to doing it, I will just swap in the correct ball joints at this time.
