Gasket between master cylinder and booster - 70 cuda??

Hi guys - am reinstalling booster and master back into my car - there wasn't a gasket between the two when I disassembled it. But I see Year One sells a gasket that indeed goes between the mc and booster.
So does it get one??
70 cuda with power discs.
Thanks for any info!

anybody?

Good morning! Most all that I've seen, and I'm NO expert, have had that gasket. It's like a soft, foam type material. It will work without it. But, it's probably to keep any moisture/dirt out. I put one in my 70 Challenger. Order it from YO. Take care, Jeff
