Are the HO BLI F unit shells interchangeable?

Hi!

I was wondering if a BLI F (A and/or B) unit chassis would accept another mfg shell?

Thanks,

The BLI F unit chassis will accept the highliner/genesis shells assuming you have the window insert/locktabs. You will have to sand down the cab interior wall a bit to get a good fit but not by much.
