Ron, I'm doing the same on my '40. Probably more similiar to your '36, but I know nothing about those. Maybe the pictures can help a bit. On mine, the green painted sheet metal is about 5/16 over the frame. I don't want to reshape or cut that so I'm going to use a 3/8" steel plate and weld the top mount to that, then bolt the 3/8" to the frame. I can also raise it some rather than bolting to the frame. One picture shows the top mount giving about 11 1/4" between mountings. I don't think that is enough. I haven't decided where to mount it yet. I got KYB KG5514 shocks. Specs on that are compressed 8.74, Extended 13.86. The Monroe 5758 is 9.38" and 14.63. I didn't take into account this style shock needs the rubber bushes. Each are about 3/4". It would be easier with a shorter shock. The selection is limited with the S1 style ends. Still haven't decided to keep these shocks yet. Have gardening duty for another couple days then I'll get back to it.
Forgot to add I bolted the all-thread to the bottom mount to see what angle it wanted.
