Thanks guys, ordered that seal off ebay.
So at least I will have "a" seal in the inventory. I'll check on the other options also.
Thanks for the links to the tools, very helpful.
Any chance one of my various other pullers will work?
I was going to try to just put the AC mount in a vice as a work stand.
I "suspect" my compressor is in pretty good shape if "mileage" has anything to do with it, it came off a 50k lemans that was driven in upstate NY where AC is required maybe three months a year.
