I bought a pretty nice all original 49 F1 with the V8 engine and 4.27 rear end ratio.
First of all, I have attached the data plate which is found in the glove box lid. I really don't know what the bottom right hand numbers / letters mean. If anyone can enlighten me on this it would be much appreciated.
Secondly, the Dana 41 with 4.27 rear end ratio leaves a little bit to be desired in regard to modern driving. 50 mph seems to be getting near the manageable top speed. Does anyone sell ring gear and pinions for the Dana 41. I would rather get the 3.73 ring gear and pinion for obvious reasons.
