I believe that I have some extra 3.8 mounts for my two 88's. I will show them to you when you meet me on Monday (04/24) to look at the other parts I have to pick up from Don and then go to my shop. LarryH
1999-2000 Pontiac Trans Sport are bolt on.. ($10 junk yard parts) there are 2 styles . (1 with the 2 mounts you need & 1 with only 1 mount bolted to the end of the trans side cover) OR you can buy them from Fierorog
