Can I get shims for a hydraulic slave bearing locally?

[ModernMuseum]

Do local stores stock stuff like this? I ordered some shims earlier this week from American Power Train, mandating that I had to have them this weekend (they sent me a kit a week or so ago and for some reason the shims didn't come in the kit).

This weekend is the ONLY weekend in the near future that I'll have help to install the engine/trans.

Of course, I just got the UPS shipping notification. Estimated arrival: 26 April. Fan friggin' tastic. Thanks APT. This project is definitely cursed. I'm probably going to kill myself within minutes of getting on the road.

Anyway, will a chevy house stock something like this?
