Kalun - Thanks for your Critique of my fabrication. I had originally intended on having 3 sets of holes in the brackets in a vertical plane which is why I created them the way I did. I could well trim them down but may not.
In terms of the quality of the steel I used - I've bought this "lumber yard" steel before and found it to be of relatively high quality with very little impurity - noted as slag or other chaf from the welding process. In terms of looking for specific alloys for a bracket that is quite easily over-engineered for the task - I was not concerned.
So - this may make me some sort of hack - but I'm a hack that's been doing it for a lot of years and so far my creations hold together quite well. Perhaps I've just been lucky!

A racecar it is not. It only looks like one. The Track use that this car will get will be limited to something well shy of 10:10's work as it will be for instructional use.
Bill - Thanks for including pics of your 930 mount! It's good to know that I'm not the first to use the end-cap studs to support the weight of the transmission by an external bracket!
Hopefully more DRB guys will see fit to contribute to this thread..
Thanks all...
--edit--
BTW - Have you ever tried to drill through that Bedframe Angle iron? It's tough as HECK!!!!
