Thnx guys
Just double checking before I order "up" some gears.
I didn't want to "lead the witness" by offering my guess....
Biggie- To clarify a couple of things, before you order up some stuff you need to know what posi-locker unit etc is in there. All the 9 inch gears will fit but if you want to UPGRADE say from a peg leg open unit you need to know what else is in there. ;)
70 351c 4bbl had rear sway bar & 2 hole 9'' housing part of the comp suspension but 2bbl didnt so u need to check housing maybe 8''.

Just checked some pictures of a H code 3 speed. It had a 9" in it. But no pictures of the rearend tag so can't help with the spline count
28 spline for sure
