Title: Power takeoff adaptor, adaptor?
Post by: Steven15 on April 01, 2008, 08:53:38 PM: I have a BBC and after the flywheel but before the power takeoff adaptor I have an aluminnum spacer. It seems to keep the adaptor away from the flywheel. Have any of you heard of this, or know where to get a new one?

Someone was doing some "adjusting" with the "shim" , could relate to a drive line lenghth issue or engine swap etc We sell PTO's for just about every concievable application you could think of ,BBCs come in 4 different configurations flex plate ,flywheel etc , the crank side is "registered" in or out to facilitate the rear of the crank post some pics of what you need or cal for tech help or "coaching Tom

Post by: Steven15 on June 20, 2008, 05:49:12 PM: I really appreciate all of the responses. It has been a few weeks since my last question. The problem was that whoever built the motor before was too lazy to go and buy a flexplate PTO, instead he/she took (wasted) the time to fab an aluminum spacer. But to all of you who took the time to answer, my sincerest thanks...and good luck.
