Rainman56 you were correct ,didnt really make much of a difference.
So made yam 450 calipers fit instead.Stops now

Nice...I know with mine the front brakes felt spongy so I ditched the rubber flex hoses and went with braided likes as well as switch to a newer master cylinder (450 one I think) as even after the rebuilding the original was still azz lol

Also sometimes when installing new brake pads they can't feel a tad spongy until they set in with the rotors.
