Body Block interchange question

[Roadster62]

I got a smoking deal on these body blocks, marked 1928-29 Part number A-5001-05. I know the long front ones won't fit, but are all the others interchangeable with a 1930-31 Roadster? Driver not a show car. Thank you, Bob

Don't have much experience with the 30-31's, but here's a diagram I saved from somewhere - appears not more than a couple of the blocks, at most, are the same.

You could probably use #2, 3 & 4. (Front to back) It's obvious #5 should be longer for more support and #1 is totally different. #3 has a cut-out for the Phaeton curtain pan (29) but it should work.

Thanks!
