i recently purchased a 65 c-10 that still has the factory 292 engine and powerglide tranny. problem is the powerglide isnt shifting into second and leaks like crazy. i have located a 350 auto from a grandmas 68 belair thats supposedly low miles and in good working order. i figure a perfect swap. does anyone know of any things to look for in order to make this swap go smoothly? should all the linkage still work? how hard is it to get it alligned again? output spline differences? etc. any advice greatly appreciated
