Hi Gang,
A not often seen assembly line correct 1970 Nova 5470409 master cylinder core with the bleeders and UT broadcast stamp code on the front machined pad available here.
Hard to find these cores anymore of course. Good stamping and the cast date is 196 - July 15. No stamped assembly date located.
The chrome is nearly all off the original Delco lid - might be able to be saved, but it is what it is, as shown. It's a recent take off, but was sitting for a long time - needs a total rebuild. Original bail wire in usable shape.
I believe UT is 1970 Nova - Yenko too

Deuce, LT-1 SS350 SS396 SS COPO 350 396 427 disc brake
A nice detail piece that sets the best restored cars apart; these are right up front for all to see under the hood.
HARD to find piece IMHO.
400.00 PPG shipped & insured to the US.
Cheers all, and Happy 2023!
Anthony
