I am making slow progress. In the last installment I posted the bracket that will hold the Holley Dominator ECU and the Hardwire PDM. Today I got a care package from McMaster Carr with some hardware.
The Dominator case is not supposed to be grounded to the car chassis. It actually has plastic and rubber mounts that are already inserted into the case. However, to isolate it more, I used rubber nut threaded inserts. To fasten the auxiliary bracket to the main bracket I used U-nuts.
Here you can see how it all fits together.
Unfortunately, the holes in the PDM are too small for #10 screws, so I have to #8 screws and corresponding U-nuts. I used a temporary support for picture purposes. LOL
