Re: PFE reefer kits R-40-20
The only PFE 40-ft steel reefers that I know Sunshine did were the R-40-10 and the R-40-26.
The R-40-14 and R-40-20 are very similar, with the -20 being 1-1/2 inches taller.
I would make an R-40-20 from an InterMountain R-40-10 (and ignore the taller height), but I suppose you could replace the roof and underframe of a Trix car and narrow the ends.
