Junky, I bought the Federal Mogul support from a local chain A&A Auto, Joe Amato's old chain of parts stores. I paid about $30.00 plus tax. I think the list is price is around $60ish.What does the Federal Mogul bearing cost, and did you purchase it from one of the chain stores like NAPA, CARQUEST, O'Reilys, Advanced, Auto Zone, etc.?
I have never tried filling the cavity with silicone, but I picked up a tube of urethane adhesive sealer for just that purpose. But after I saw how heavy the rubber is, I'm going to try it as is, for now.Have you heard of the trick of poking a hole in the rubber and filling it with silicon?
I have never tried it, but I never beat on my 63 when I had one.
Now scene Tom has me pounding on these X frames, I just started with the poly mount, then when to a one piece shaft.
