Yeah! That's where I came from Carl. Old oxy-acet guys who could do car restoration with just their torch and a few hand tools. The bell housing is very brittle because its made out of Cast. That would be a consideration. The housing I use on my test stand is cracked at one of those bolt holes.
Another reason to not use it, without adding about 1/4" to the width of that, its pretty narrow there. BUT if you have a torch, just torch out a piece of scrap and go to town! Or, go to town, get the piece of scrap, then do it.
