After 40-ish years have elapsed on our classic and "antique" vehicles, I seen that the AC Delco clutch hydraulics for our cars have gone on closeout status at Rockauto, so better get them while you can.

Rockauto:
AC Delco Clutch Master Cyl. #18M2131
AC Delco Clutch Slave Cyl. #18F85

The AC Delco parts I received say made in USA and look to be of quality. I'd be inclined to believe them to be OEM parts.

From research on this site, I've also pieced together a stainless steel braided hose setup for the system to replace the plastic line.
Nothing below is confirmed as fitting. This info is given "as researched" only.

All of these will be going to my "just in case they become obsolete" spare parts inventory.
(The special -4AN adapters at Summit seem to be in short supply also.)

Summit:
McLeod Racing Adapter Fittings for Clutch (Straight, -4 AN) #MCL-139026
McLeod Racing Adapter Fittings for Clutch (90 degree, -4 AN) #MCL-139027
McLeod Racing Hydraulic Line for Clutch (-4 AN) #MCL-139100-30


Hope this helps someone.

 

Rumor has it that the new vehicles will no longer have manual transmissions - not even an option.

 

Won't be too much longer until new vehicles won't have automatic transmissions either, all CVT belt drives. And I'd guess the torque V8 engines will be only in heavier trucks. Regular vehicles are becoming appliances really quick.

 

That about sums it up perfectly.

 

I might grab a set. IIRC the LUK master was made in the USA and when I replaced mine the Advanceauto replacements were aluminum body instead of factory plastic
