An excellent write up and I thank you. Two questions however. Will this new gear ratio change anything as far as the transmission goes such as requiring higher revs to start rolling?
A friend had put a 3.08 rear in a 47 Chevy car and he had to rev the engine higher than normal to get the car rolling.
Secondly I see a part number for axle Speedi-Sleeves. When I had to pull the axles on my 53 about 10 years ago they were badly worn from the seal. I asked many people about the sleeves and was told they were not available and if they were they would not do the job. Some suggested sweat soldering or welding the groove and turning it down. I had used one on my crankshaft where it goes through the timing cover and it worked well. I ended up scouring the countryside looking for axles in better shape than the ones which were worn.
