yep. the speedo follows the rear end.

this will include the hash marks for shifting assuming it comes from a diesel equipped car. if not the hash marks will be too high.

on the other things it sounds like you have it all. did you mention radiator? i dont know if the 280 rad is the same as a 300 or not. i doubt if it is. but it may work anyway. anyway you can try it and if it gets hot too easily you can always replace it later.

i ran the 240 rad for a while after the 300 conversion because the indie didnt understand he was to change it. and it wasnt dramatically bad but it didnt cool adequately under heavy stress conditions.

good luck
