Hello all,
It appears there may be trouble getting parts from Schumacher or MoTech (new owner) and I'm wondering if anyone has experience with the swap mounts from Holley/Hooker?
What bothers me is that the Schumacher mount shows applications for "73 and Up A,B,C,F,M,J-body" and the Hooker part# BHS571 is for "1973-1976 Mopar A-Body".
They're similar, but the Schumacher appears to move the mount more forward (and therefore, the engine further backward).

Does anyone have any thoughts on these?

For what it's worth, I received a message on 1/11/22 from MoTech Performance that "We don’t have those yet, it’ll probably be about 4 months until we get around to the G3 Hemi stuff".
So, no Hemi mounts until May 2022. Suck, but that's life.
I'll probably buy the Holley mounts and see how well they fit.

Small block to big block mounts are finally available, for anyone that’s been waiting.
No other options are available as of yet.

Finally, some updates after getting my Holley oil pan installed. The Holley motor mounts are juuuuuuust a bit too far back for a bolt-in fit.
The pan just barely hits the welded seam of the K-frame. A little cutting and welding will easily clear this up. Overall, not a massive problem. Even if the frame was still in the vehicle, modifying the K-frame wouldn't be a deal breaker for most of us. I'd rather cheat the engine forward a little bit as this should help transmission swap issues in the future.

That K member can be trimmed and welded or you could heat and beat that flange down then weld it to itself. Either way can be done so it looks good…

Bingo, I figured I'd cut/grind off the flange and just weld a flat plate joining the upper and lower sections. Easy-peazy!

If you have the K frame out of the car sandblast and weld all the cracks….

Thank you for the pictures. While I love my current setup it's nice to see what it would take for other options.
