My brother has a 1950 in good shape. he was going to streetrod it, so it has had ifs frt suspension and new rr suspension installed, no rust in trck and pained flt black, lots of new parts. Asking $5500. you can see pics on craigs list in AR or racingjunk.com
there are also 2 - 48-50 F1 down the road still all original that are probally buildiable trucks. I think he is asking $1k. Not sure will have to check and get back. Bad part is it's a pretty good drive form NY to AR. Jim
