well i can't help you with the dimensions, but your on the right track with using eastwood products. they have all types of paint to use from the correct color of the altenator, to the correct black for power steering pumps and brackets. if you haven't already, just get one of there books and that will help you out with what you need. i don't live to far from them and one of these days i'm going to take a road trip down to see there place, and probably take my credit card too. they have a lot of nice stuff.
