Who's are you running !!?? Mopar or no car.

That looks nice. Is that a milled/billet piece, or a milled casting? Is it a one off?

Seems like motor plates with today's CNC stuff, they would be straightforward customer customizeable, and a profitable niche market if promoted, especially if someone had a decent library of different basic designs of various solutions, beyond the standard stuff out there today.

It's not like its 5 axis super tolerance machining, and the raw material is basically flat plate.

What am I missing, or is this already resolved that i am not aware of?

It's a piece of billet. There are a lot of them out there. It would be very easy to indicate all the holes and copy it. I've thought about it several times to make my own, so I could change a few things.

Each hole is helicoiled.

It's recessed for the jesel belt drive too

Mine was copied from a Competition Engineering piece.
I used it for a template because it had been drilled out for a lot of stuff I'd never have on my car.
A mill and rotary table helped get a nice radius on it , so it was labor intense , but turned out alright.

Here are a couple of different options

Nice pieces out there !!

Dou you install a rear piece too ?

Can you get rid of the heavy K member when bolting the plate to the front frame rails ?

Any one using studs !?
