DRB transmission mount. What is it from?

[Lee]

Hi. I'm looking to stiffen up the rear mount on the transmission in my DRB 40. I get a lot of judder below about 2000 revs requiring lots of clutch slipping round town, and on the rolling road you can see a lot of vertical movement of the rear of the transmission when load is released or applied. So I need to identify where does the current item come from. I guess it is from somewhere off the shelf in Australia, and I hope someone out there with a DRB has already identified what this item comes from. Ideally then I can find an uprated/ poly version. The rubber is bonded on one side to the metal frame and on the other side has 2 threaded inserts within the rubber which are 7/16 UNC. If you can help please chime in. Thanks.

The overall size of the bracket is approx 133mm x 57mm x 48mm.

Lee, look here. I’m on dialysis at the moment and it’s hard for me to search. But that looks like a regular Chevy tranny mount.

Agreed… I’ve seen many GM mounts just like that..

It is used on Ford Mustangs, Galaxie... it is the silent block that goes under the 4 speed manual transmission (Top loader)

I liked when I put in transmission mounts, a picture of a GT40 came up.

Now that I look at them, it appears the one for the Chevy and Ford use the same part number. I may have one in the shop I can measure. I have a procedure at 8:00am. Hope to be out of the hospital by early afternoon. All goes well, I can look and measure for you.

Although no dimensions are given, you could contact their tech line.

Thanks very much and best of luck Brian. Looks like it is the Chevy mount, not the Ford mount. In the Energy Suspension range, looks like the options are 3.1108 or 3.1132 or 3.1158. I think 1108 and 1132 are same height but difference is zinc or chrome finish. 1158 is shorter in height and probably a better replacement to allow for the fact that the polyurethane will not sink as the rubber does. I have a spacer already in my setup so the standard height should be OK.
I have ordered a chinese version on Amazon UK for next day delivery. I will report back.
Thanks again.

I ordered this from Amazon.
2 bolts were supplied as shown, BUT they do not fit where shown. The bolts supplied are 7/16 UNC, but the threaded holes are M10, so the bolts are pretty useless.
The polyurethane starts not far below the bonded in steel plate so needs quite short M10 bolts, or lots of washers, but I got it fitted OK in the end.
Road test was positive. It did improve the situation, but not completely so I will be looking at the engine mounts in the future.
