You may not find your OMC units.<br /><br />The best you may do is to find something that bolts to the 3.8 that you can make work in your OMC application.
As yoced stated, you will have to find some aftermarket manifolds that will work. Try this site, OSCO motor corp for a set of GM V-6 manifolds.<br /><br /> http://www.oscomotors.com <br /><br />Good luck!
Thanks, no. I don't like GLM as a corporation. A personal thing. I'll have to let you find them yourself. There are plenty of folks on this forum who like them though, and they may point them out to you.
