I went out and took a look at what I had in my shop, I sure have used a lot of different makes and models of mounts but the GP adjustable is the hands down winner. I pretty much do everything Chuck does but I also take a cut off wheel and when I get the engine mounted I make a center line between the two halves. No real reason to do this but I started doing it years ago to line them up before I hit them with a daub of CA. Then I removed the engine to mount the mount onto the fire wall. I catch myself doing odd things like that just because I have done them for years, no real reason, just bacause!!
