346 brake master cylinder, W T stamp?
 

My 30 year old repop power disc brake master cylinder has bit the dust. I want to replace it with a GM correct 346 unit. My cars build date is first week of June 67. Should the unit have the W T stamp on the front pad or is it okay to not be there?
I have found them both ways, I was always under the impression that all used on a power disc brake cars had the W T stamp.
I’ve got a message into Mike Gibbons but today being a holiday I don’t expect a return message until later.
Thanks,

WT is the correct master cyl for 1967 & 1968 with power disc brakes. I've seen several but I think it was determined that there was no date code in the casting. I would look for one with WT stamped. Mike can get you going in the right direction....Joe

All power disc 67 Camaros had the wt on the master.

I’ve been wanting to do this change for a long time and had researched this before. I wanted to hear what you guys thought. CRG says the 67 power disc brake Camaros had the W T stamp.
Seeing the 346’s without the W T kinda threw me off. Appreciate it guys.

Replacement master cylinders didn’t have the wt markings.

That’s what I had suspicioned, the ones without WT were replacement units.
Thanks,

346
