I've looked online and the parts store can't seem to find out what size I need either. I've got a 1980 RX-7 that needs a new set of front wheel bearing dust caps. Does anybody know where I can order them online or at least what size they are? (I'm not sure if this is a part that comes in standardized sizes that manufacturers pick from.) Also, I'd appreciate the sizes for the rear dust caps for the '80-'85 years.

Thanks in advance.

 

I'm not familiar with the size,but I would get a caliper and measure the inside where the caps sits and then see if a regular parts store would carry them.
Another suggestion is go "used" and place a Wanting to Buy Ad up in the 1st Gen Parts section.

(I usually don't allow WTB parts but you were asking about size..)

 

I bought them from MazdaTrix recently, MazdaTrix has them in stock, great guys to deal with, their prices are low too. Very knowledgeable staff.

Thanks pdxgen1, I have the parts on order now.

I appreciate the help from both of you!
