I searched and searched but i couldn't find which roller rockers fit the pedestal mount 3.8L engines? Someone told me but i forgot. I tryed to put the ones i got for my 99 5.0 engine on it and they didnt fit.

No doubt these will fit for sure but they are a bit on the expensive side...
Did you search for Mustang 3.8l Roller rockers? I know they make them, and depending on what year motor you have, they'll fit.
I know that they have the super over priced sets, but i think i remember a set that fit a cleavland or 351W that fit the 3.8s and were like $150 like all the other pedestal rocker sets
