Powersteering conversion issue

[Charley7]

So i have a 1971 c10 2wd. I’m trying to convert it from manual steering to power steering. I’ve read the swap info section a few times and searched this forum. I have steering gear 7802644 and found I needed a 6131 pitman arm. The issue is that the inner tie rod hits the crossmember before I can get the pitman arm on. It does have wilwood drop spindles on it.

Thanks for any further info.

Charley.
