RPP SD90 Phase I shells

I have two RPP SD90 Phase I shells. Will these fit on a blue box Athearn SD40-T2 chassis? Are they the same wheel base? Just wondering.

It would be nice if they were then I would just have to worry about finding a set of the correct sideframes for the trucks.

Never mind. I got my answer.

SD40-T2 = 70’ 8"

SD90MAC = 80’ 2"

The SD90 frame sells for $15 at the PPW/A-Line website (item 90901U). They turn up every now and then on ebay.
