OK, but the front bearing retainer and TO bearing will need changed over to the later clutch setup.

Be sure to check the length of the front cover as well. It has to be a bit shorter for use with the TR6 clutch. Otherwise, when you step on the clutch, the hole through the center of the PP diaphragm closes up and hits the front cover.

I'm sorry, I forget the dimensions offhand, but you can check your old cover. Or just swap it in.

I put a tr4 atype in my 69. Fit perfect with no mods and used a tr6 clutch etc.

The TR4A type will work fine. It is the TR2,3,and 4 that require adaptation to the diaphragm type pressure plate.

You're correct CT 30915.
It also has the thinner flange which might be why it cracked, dropped maybe and was welded up.
Notice the rubber boot on the slave, 1 year old totally rotted. Off topic but my wiper blades were 3 months old and the rubber just fell apart, never used, self destructed.
