are you going to cut that tube over the engine and weld flanges on each side so you can un-bolt it?
I was going to order some of those cool tube clamps to make it removable but the way I look at it, I've owned the truck 8 years this fall. The engines never been pulled once. I'll make it removable the day that engine needs to come out or needs work. I've never had to touch it so I'm just Gunna burn it in an call it good.
