1969 hemi brake booster rod to firewall boot

[INTMD8]

Currently (as I bought the car) the booster is installed with no boot.

I have a boot but it is round and the hole in the firewall is not. (kind of an oblong hole).

Am I missing a plate that should convert this hole to round for the boot?

Thanks!

Ok, I think this is what I am missing. If anyone can confirm this is what the boot clips onto but I think this is it.

Didn't work out. The plate I bought has a much bigger bolt pattern.

Anyone know what I need here? Thanks

I don't know the answer but I'm helping someone assemble a 69 Hemi Roadrunner with PB and I may be able to find out what they used this Saturday in the event you don't get an answer before then. It does seem I remember they had to modify a plate for the PB booster so they may not be able to help - just have to see.

You have my sympathy with power brakes on that car. It's been a royal headache on his. I think if it wasn't for installing a hydraulic cam he would have converted to manual. Just changing that back plug is enough of a headache.

You need the correct firewall plate for disc brakes with the round hole. Drum brake cars had the oblong hole. You can find new plates on Ebay.
