71 c10 with 73 spindles alignment issue
 

I have a 71 c10 short box and i has a set of 73-86 "western" drop spindles from another project truck along with 1 inch cpp drop springs

I checked my old paper work and they are 73-86 so i changed my upper ball joints to 73+ and my it still needs to come way out on the top for more camber its leaning in way to far.

My question is can you use 73-86 spindles on a 71 ? from what i read I should be ok as long as the ball joints are changed.

I was wondering if i can use 73+ upper control arms on the 71 so i can buy the offset control arm shafts? or if i am missing something .... i have lowered several of these with no problem but never tried the newer spindles on the older truck...

Pictures would help. Are there any shims in behind the upper control arm shaft? Your set up you did should work without any issues. I did a similar swap on my '65.

Yes, the upper 73+ arm will bolt up to your '71. That may not solve your problem...
