Yes the new cups are shorter they measure .200 compared to the US which are .360. The tapered area of the short cup is .130 wide the US cup is .230 wide.
Another difference the shorter cups have a series of of ribs around that shorter .170 tapered area this makes the sealing surface almost non existent.
There's also another problem I'm experiencing with the wheel cylinders they do not retract correctly compared to the original US wheel cylinders. This creates a dragging brake shoe issue
I'm going to check and see what NAPA has will give an update once i have them in hand.
This year makes it 50 years I've been driving the roadster updating parts and having an issue sure sucks. I'm going to rebuild the original wheel cylinders to get things back to normal.
Thanks to everyone for your input. I'm off to NAPA
