360 motor mount measurments

What brackets do you have now? Trying to modify Van/ PU brackets would be a LOT of work

Here's what I did. I had a set of 360 brackets (they are not mounts, the mounts are the rubber part)

I took my stock 67 273 brackets and "sprung" the larger PU brackets over the top, so they were nested together with the holes lined up, and bolted them together.

As I recall, I only had to drill one extra hole on the passenger side bracket

On the driver side, I used a piece of strap iron to make up the top bolt location for the bracket.

Pretty easy, all you need is a welder, a drill, and hacksaw.
