Square cut caliper seal

[TexasSpider]

I was rebuilding the front calipers and ruined one of the new square cut seals (the seal inside the caliper body that goes around the piston). I can order another inexpensive rebuild kit but that means waiting for shipping and probably next weekend.

I thought maybe there is another car out there which uses the same size seal as the spider and autozone/o'rielly's/etc actually carries. Any chance of getting lucky on this?

I did some research and no luck on alternatives so I ordered a new seal.
I learned the hard way the proper way to rebuild the front calipers.
