Re: Mounting, anyone tried...
The 4575 list their 9525 mounts as compatible. Those are the junky 73-and older style mounts, inferior to what was used in the third gens.
The 4203 has the more modern style mounts. But, since the third gens sometimes have different height clamshells, I think you'll find they put the engine close but not perfect.
Personally, I like: Spohn brackets at the frame, and 4th gen mounts (bolt to the engine) They make service of the mounts a whole lot easier, and are set up for the F-body pan to clear.
