Anybody know if there is a difference between 73-87 rotors\hubs and 71-72 rotors hubs?

cdowns · 01-01-2007, 08:05 PM

pretty sure 71-72 are by themselves and are not interchangeable with the later years

I want to say the 73 - 77 or so was thicker than the old ones... and then 78 or so went to metric lugs...

Larry,
call your local parts house and do a numbers check, i've done that in the past when i was unsure. there is a hd and a ld in the later ones.

NAPA Part # UP 85537 fits 71-87. In 88 started metric lugs.

Woodridge, thanks a lot. I was pretty sure the rotors were the same, I just wasn't sure about the hubs\bearings.
