I happen to have spring perch's from Speedway, think they are Mopar, but it had 3 holes in bottom, moved centerbolt to forward hole, made new lower plates with the shock mount bolt moved. Moved the rear about 1 1/2" rearward which centers it in the fender opening. Waiting on the lengthened drive shaft and will take after pictures to show the difference. Still looking for a bench seat that will fit a little better than the 88-89 full size chevy pickup at 58", it leaves little room at the door, and if I want to cover doors inside later I couldn't, but the riser is just about perfect. Will look at Fall Carlisle next week end 54" would be perfect, I know Dakota is 51" and I think Ranger is about the same, Tea's are a little $$ I was thinking maybe Caprice, but don't know, Zeke
