ARE ALL OF THEM THE SAME ON 12A FIRST GEN'S? LOOKING IT APPEARS THAT 79 AND 80 ARE DIFFERENT AND 81-85 ARE THE SAME. ALSO DOES ANYONE HAVE THE #'S OFF THE 1'S NEEDED FOR 81-85 i HAVE A COUPLE OF DIFFERENT ONES OUT IN THE SHOP AND HAVE NO IDEAL WHAT THEY GOTO.

 

i think all 81-85 are the same, but im not 100% sure. i KNOW 79-80 are different.

 

Yea Well All Mine Are The Same # So Just Needing To Know Which They Are. I Ll Go Out And Get The Numbers After I Eat.

 

the difference between the SA and FB calipers? the SA ones are HUGE and heavy as hell and look odd. the FB ones just look like normal calipers.

 

ok 3 spindles 3 different #'s

2 R O5J 2005
1 L O5K 2005
2 L 01A 2005

2 ARE SMALL BEARING 1 IS LARGE BEARING. KINDA FUNNY MY SA PASSENGER FRONT HAD BEEN SWAPED TO BIG BEARING. SO CAN ANYONE HELP ME FIGURE OUT WHAT I GOT HERE?

 

If they attach with a bolt at the bottom, and slide onto a pin at the top, they're 81-85. I believe the casting number 2005 are all the same.
79 and I believe 80, use 2 plates that slide in, and are held in place with 2 R clips each.
