found a company that sells them they are Kartek they are 15 or 16 bucks each and the a porshe 930 bates style cv boot for those that run into the same problems
All Pro used to sell the inners because the instructions told me I had to cut part of the boot off the original to fill the Tulip portion on the inner in order to use the new LT boot. I knew there were a few other sources out there and Kartek is another good one.
Check with your local axle/driveline shops. They should carry something. Inners have some room but the outters are close and can rub some aftermarket high flex boots.
