Ok i'll try to make this short. I had my semi float rear 60 for sale and it hasn't sold,so i decided to build it using one of the 70's i have and make it a full floater. When i started taking some measurements i realized the pinion on my 60 is offset by 11/16th". I then measured the 70 and i found out the pinion is offset by 2 and an 1/8". Is this normal? It seems to me that if the drive train is centered in the chassi,that the rear pinion should be centered also. Am i missing some thing here?
