-OMGosh That thread/link helped so much and lead me in another direction!!

OKAY now after climbing out of the rabbit hole I have the answer!
The 4.7 bracket (53020884) will not work bolt spacing for the pan is the issue.
The part we (or I ) need is the (53021491AA) This is cool that that this was found, but it sucks cause I've wasted 6 months waiting for Holley to do something-- :poke:

Nice find!

Can you post the center to center distance of the bottom holes so I can figure out if it will work with a TR6060?

BTW, how did you confirm that the 4.7 one won't work?
