The Stovebolt Site Forums The Shop Area Engine Shop Rear-End Swap?

You may be able to have the 5 lug, re-drilled to 6. If something happens down the road you will always have to have one drilled. But the amount of time and cost might be better spent finding a 10 or 12 bolt chevy rear end from the 70's. The 12 bolt I found from a 77 burb has 2-3/4'' wide HD brakes, a BIG difference. The e~brake cables are a near match in length (for my 3100). We moved the axle back 2 to 2-1/2'' rather than the 'kit' has @ 1-1/2'' from chevy duty. I had to make an adapter to fit the end of the E~cable outer housing to the 3100's stock cable adbutment holder.
