A 6 cylinder and 8 cylinder have two different control valves. a 6 cyl has a screw off type control valve (like a 67-70, but different). An eight cylinder has a the control valve built onto the drag link. Virginia Classic Mustang can rebuild your control valve for $119.95. Or if you would like one out right, it is $119.95 plus $250.00 for a refundable core charge. I hope this has helped

I am rebuilding my v8 66 control valve right now too. You can get the complete rebuild kit (minus the bronze sleeve) for about 35.00 from national parts. The sleeve is like 10 bucks.
Not a big deal to rebuild either.
And yes, the 6 cyl and v8 are different as replied to above
