I recently came across this idea on the internet and copied it. I plan to make it and see how it will make the job easier. Obviously dimensions of the blocks will differ for my 3GM30F but you get the idea. Simple to make and should save the aggravation of trying to maintain tension with one hand while holding the tools with the other 2 LOL !

I would be interested as indeed it does look a whole lot better...but I wonder about the length once assembled. Too long between the crankshaft pulley and the impeller pump and too short between crank pulley and alternator ? Have you seen specs anywhere ?
amazon says 4.5" to 15".should work
