KR500, yes, the 1" is what I want, but another member here may have a MC and booster that will work so I may go that direction if it's 1". The Bendix is an option used for years and can be had at O'Reilly's Auto Parts in many other places for under $40. I was also reading through SoBills parts list spreadsheet that covers probably 4 decades of Pantera parts that work for different systems on our cars. There is also mention of a Mustang SVO master cylinder that is a 1 1/8" bore that mates to a 1980s Lincoln Continental master cylinder booster unit. Not sure of the benefit to going to a 1 1/8 " bore. So far I've not found any specific part number for that item. But supposedly it bolts right in. I'll post back here if I find it.
