AC Compressor O-Ring

[Hawg_man]

I need the size/number for the o-ring where the high pressure line mounts to the compressor. 1974 Plymouth Satellite, 360 V8. The old one blew and can't be measured.

I forget the number of the 0-ring I used, think it was a 21, but I found some at local auto parts store that are 15/16" ID, with 1 1/16" od and 3/32 thickness that worked well, and this is real close to a 21.
