hey guys i was up late last night and found a print for making a adapter plate for mounting the TII turbo mani to a 12a. the print did not have all the dim's need so i figured id use a cad program i have and figure it out for you guys.

parts needed. to make this a 13b flange and 12a flange.
5 inches of 1.5 id tubing. i was reading this would be the best tubing to use so it keep the exhaust speed up. use what ever id tubing you want tho.

i do not know who made this print in the first place so please do not sue me lol.

mark the tubing at 58 deg then slide protractor up 2.353 inches or slightly less then 2 and 3/8 Th's. then cut on your lines and repeat. i figured id help you guys out since iam going to be trying to turbo my 12a.

(i know i didnt use all the correct wording but hey i only got 2 hours of sleep cause this stuff was bouncing around in my head.)
