BC Broncos brake booster

[OverBudgetBronco]

I purchased a BC broncos brake booster kit back in 2001.
Booster needs to be replaced, I can't find anything online, but front what I recall it is a mustang II brake booster.
Can anyone confirm a part number for the correct replacement booster?

Thanks!

The early bc kits were mustang 2 boosters. They switched to the newer gm(?) style due to availability.

You might get a better response if you can post up some additional details and/or a picture. FWIW, the stud spacing for the master cylinder is 3.4" on the GM units and ~3.2" on the Ford units. The 1974-1978 MII boosters are a dual-Ø7.5" units and have a somewhat unique look to them, so they're fairly readily identifiable if you can provide some pics, or you can compare yours to pictures at online auto parts stores.

Yeah, what I have doesn't look like the mustang II booster, that's why I was asking.

Best I can tell from photos, I think I found it. Hopefully this helps the next guy.
