I really dont wanna, like, advertise... watever...

I've found a mustang part supply w/ more of a selection of parts for mustangs 95 and prior... they have alot of 5.0 stuff and 1rst 2nd and 3rd gen mustang parts...

the website is no where near as nice as mustang tuning...

actually mustang tuning has got to be the best for the 4.6 generations...

but these guys got a big selection of the older stuff than here...
I bet you could find the parts you want there and then the mustangs tuning guys will hook ya up even better...

I'm just posting the link for SHOPPING purposes then heres an even better link for buying purposes
