Are the weights on the flex plate or the tc? The only plate I have been able to find is for a 727 by B&M.

The epoxy that is used for marine applications are pretty good, like the stuf they use to hold the magnets on the flywheel for the stator on an OMC engine. Ya kinda got me on that one. 76' Volare, 5.9 magnum w/Iron heads. New best 10.68 at 123 mph 1/4 mile.
