So what will it take to cut out about 16'' for an AV8? Why I want to go this route, well the banjo I have came from a well cared for car that was last registered in 1951 then stored in a barn to be restored from the original owner that pasted in the 1970's. The car was taken apart but never back together. The 10 spine banjo is in great shape, tight no leak and still full of fluid. The wheel baring races have no marks no pitting. I really don't want to pull it apart just to put in a worn out 6 spine and ring gear. Also is this banjo and only year with 10 spine or could I find a 33-34 driveshaft with 10 spine?
