Re: Front disk and drop question

I took the entire front suspension off a 1971 GMC, but that was like 15 years ago, little harder to do now-a-days. You can use an entire set up off a square body, but stuff like ball joints and tie rod ends are different sizes. Not a huge deal, but when ordering drop spindles, etc. you need to match everything up. I believe you can just install 71/72 upper and lower ball joints in 73+ upper and lower control arms and order a kit for a 1971/72 C10.

I'd recommend to just go all out and do an ECE 4/6 drop.
If you're keeping 15's, I'd recommend not using the 2.5 " spindles and stick with the 2" spindle and 2" spring if you plan on keeping 15's. With 15's there will be a little bit of grinding on the brake caliper, maybe a tiny bit where the tie rod bolts up, but with the 2.5" spindle and 15's I had to trim a good bit on my lower A-arm. The 2" spindle will reduce that.

I stuck with 6 lug and rallies as well. While a lot of 17/18/20 wheels styles have come and gone, I've been rolling the same wheels for 15+ years.

Top pick is from around 2006, 2nd pic is recent.
