Ah, nothing quite says "Business" like grade 8 bolts and primer paintjobs.
I now plan to do an additional support bracket, wrapping from the bottom of the flat bracket up and around to the intake manifold, basically 'belting' the motor in place. I do not like how much slack is in the lateral momentous (It can twist just by hand, but is otherwise in there tight) so I'm going to play it safe here.
Don't want my motor twisting itself apart and damaging itself, or my engine
But yeah, when my idler pulley arrives next week it should be the last time I have to work on that front one. Then just the stay brackets to triangulate it and fabrication should be done. I can also now get dimensions for my custom pulley made now, and hopefully will have that one soon!
