Wheel base on a lowered SWB 1970 GMC leaf spring truck

Hi,

I am working on a 1970 SWB GMC truck (rear leaf spring). This is my first lowered truck and I have flipped the rear axle and notched the frame with a lowered the stance 5"/3" rear/front. While centering the rear axle, I found that the wheel base is off by 3/4" (114.25"). After checking, it appears that the after market spring center pins are moved forward by ~3/4" (should be at 24" and are ~23.25'), which is where the problem is. I am about to pop the perches (not yet welded) and move the alignment hole 3/4" to compensate, but I wondered if it might be better to leave it alone. Anyone have any experience on the leaf spring flip and if moving the axle forward 3/4" is OK?

Thanks
