Drum MC to Disc MC conversion

The Disc MC is larger and heavier than the drum MC. Is that not a big deal, or do I need to provide additional support or some kind of bracket for it to mount to the firewall?

Thanks,
BH

Not sure what your'e comparing. They are both the same size with only bore size being different.

To answer your question NO additional support is needed.

Re: Drum MC to Disc MC conversion

The Disc MC is a bit larger overall and heavier. I already threw out the drum MC, so i cannot do a comparison photo or weight comparison at this point. But it is heavier. I was skimming through one of my Camaro restoration catalogues, and came across a MC firewall reinforcement plate. I haven't read anything on it, just figured if they made the part, there must be a reason for it. So I thought I'd ask in here, figuring some of you guys must have knowledge of it.

Now me being the impatient person that I am, I just bought one from Inline Tube. Here is a similar one on eBay. https://www.ebay.com/itm/64-74-GM-A-...lZdkAc&vxp=mtr

Won't hurt but I've never used one or seen one used.

As you can see in the Ebay item pic the MC bolts to the studs and sandwiches the firewall. I don't see what the reinforcement plate is reinforcing.

Re: Drum MC to Disc MC conversion

By the looks of it, I figured it was reinforcing the metal around the studs. To keep the studs from pulling through the firewall? In the end, I went with the thought that it can't hurt as well.

Dont need it.

They weren't put in by the factory and they've gone 50 years without problems so it doesn't need to be done now.
