Anyone know back spacing of 15x7 truck rally's?
So today I installed ECE 2.5" drop spindles on my '71, after it was all together I went to put the wheels on the they are rubbing on the spindle where the tie rod attaches to the spindle. The wheels are 15x8 truck rally's with 4" back spacing and I had no issues when the truck had stock spindles and drop springs. I tried researching the back spacing of 7" truck rally's but everything I found was about the corvette rally's. I'm hoping that I can get away with some 15x7 rally's. So if anyone can confirm the back spacing options available for 15x7 truck rally's I would appreciate it.

Save on wheel shopping and swapping, get some 1/4 inch spacers.
