The sad truth? IE C10, G10*20. 84 as the sample (I believe 70's may show that the 10 was 4.75 wheel lug pattern and 154 pad, Remember they made early G20 6 lug much like the trucks!) Lower BJ 6117, upper 6136 all models, you will also see they use the same A3, A5 wheel bearing. The brakes will also work on many 70's to 80's cars, so yes if you see 71-76 impala you can use the rotors and calipers. Want to be weird try using mid 70's caddy rear caliper and add front parking brakes. Want just a 1 inch drop on the front end? use same 70+76 impala lower BJ and see what rubs. My brother just brought home a 66 C10 from the looks of it he could take my whole 89 G30 front end and go 8 lug! Some tweeks may be needed for the steering and sway bar? Only when you get to the 30 things start getting Heavy Chevy. My 89 is weird the frame rails are straight from the front door back, the front leaf spring mounts are bolted on. My 84 G20 the pass. side frame rail combined the side door rail and the front perch was welded in You can mix and match all day..

Ok Guys - Thanks for the input.

Here is where we are at this point:

The CCP drop spindles I mentioned above are a direct bolt on for a G20 van. They offer a 2.5 inch drop which, with factory springs, make the van sit just right - if you cut your factory springs the tire clearances on a 235/60R15 get sketchy. The factory calipers and rotors are a direct fit. The ball joints and tie rod ends are identical. The steering tie rods ends go in to the spindle from the top, just like factory, so no weird bump steer.

As far as weight carrying capacity - The CCP spindles look considerably heavier than my factory units, and I am not planning on towing anything or carrying any excessive weight. I think that they will work without compromise.

Bottom line for me - Using the CCP drop spindles are definitely the way to go. You remember all that modification I did on the lower control arms? They ended up going to the scrap metal pile. I had to get another set of lowers from the junk yard and use the factory ball joints, which by the way, are quite expensive. I cried to Western Chassis about returning the $450 "kit" what they sent me and after a lot of red tape they issued a RMA to send them back. (customer service is not their forte) It cost me $240 to send those heavy rotors and calipers all the way back to California, (I am in NC) and I have yet to see the credit issued, so I disputed the charge on my credit card.

Hopefully this information will help some of you avoid all the expensive mistakes that I have made.

I am using CCP 73-87 tubular upper arm on my G30, just had to change the ball joint. It scared me at first, now I don't even think about it People need to give more feedback to the aftermarket so they can start listing what works on the vans.

Absolutely agree to that. I think that as demand grows we can garner more attention.

Hi Baker, Im new to this Forum and loved your info on the G20
Im picking up a 1993 G-20 this weekend and wanted to find some info on lowering it using the drop spindles. I like your information.
Was wondering, after a while running these, how are they holding up?

Also, If I want to lower my van 2.5", is there anything else you recommend replacing?
Thanks for all the good information.

I will begin with the spindles
1. Classic Performance CP4S4 - Classic Performance Drop Spindles
