mounting ears - 5.9 5.2 any differences
short update...
driver side: if you have an early a-body mount you can use it, i only needed a 0.075" washer
passenger side: the magnum block has different ear lobes compared to a 273/318 LA-Block, so lower lope on the rear is missing and instead of that, it has one on the front side.
so you have to modify the bracket - first i mounted the orig. bracket and made a cardboard template from the missing section/part
then copied it with some metal parts laying around and bolted it onto the orig. bracket. to make it a bit more stiffer i welded all the pieces together
