Questions about Lionel 21 inch passenger cars

The Lionel 18" and 21" cars share the same cross section. I have used full width diaphrams from a 18" car on a 21" car. I assume the standard diaphrams would work as well.

I hope that  you post some photos of how you converted these cars as I have one that I would like to convert.

Pete,

Thanks for your help, I ordered the parts today!

I will.  Right now I plan to use MTH 2 rail trucks on them as opposed to NWSL wheels.  The bearing caps seem to fall off the stock trucks pretty easily.  They look nice, but there doesn't seem to be a good way to keep them attached.

It also looks like they are pre-drilled for KD couplers so that makes it easy.  My main concern now is if those diaphragms gap on a 60 inch radius curve.
