Is there any difference between the 12a and 13b clutch slave and master cylinders?

 

nope.

78-85 are all the same bore size.. only difference is 78-82 have a different size thread for the clutch hose

 

Thank you sir, as always.

Not quite right.

'79-80 have the odd-thread hydraulics.

'81-82 12A and GSL-SE are the same design as '79-80 except with the "normal" thread hydraulics.

'83-85 12A have a different casting design to make it easier to bleed the clutch with the beehive oil cooler in the way.

They all do have the same bore size, same internals, and they all bolt up the same way.

 

i need to get rebuild kits for my slave (i think a new one is just as cheap). master and brake master cylinders. those brake master cylinders are kinda pricey.

nevermind, they arent that bad on rockauto.com

 

i just threw in a new one yesterday, seems to be workin but havent actaully tried driving it yet
