Early built 69 ss chevelle master cylinder

[chevyman0429]

Would a January built 69 ss chevelle still have the BA stamped master cylinder? Been looking for a core for this car but can’t find any BA stamped master cylinders any earlier stamped than the 100 day. Thanks

Yes, but I'd be looking for a 330ish number for late '68. I've had a few around that number, but currently have none.

Well I guess I’ll be looking alittle harder for an early one. As far as the year of the master cylinder are the dated other than the Julian date and the BA?

I've seen them out there with julian dates in the 300s. Here's an NOS one I saw on ebay about 15 years ago. Notice a faint stamp of 335 upside down next to the BA stamp. Haven't seen something like that before or since then. You can't see the cast julian date on this one, but I'm betting the 335 is a manufacturing date? Phil
