Have you ever driven a pre-1977 Jeep in stock form at highway speeds? Actually the steering was sorted out for the most part by '72 in the CJ's. The early Ross linkage system was scary at best when new and time and miles were not kind to the straight cut steering gear, joints, pivots and bell-crank.
A 2wd beach cruiser sounds good to me, shoot me a photo. I have a total basket case of a '50 VJ (Jeepster) I may do something similar to. I have a crunched '98 ZJ 2wd from Florida with a v-8 and all the toys.... Not a good pan-off swap because the dash/body is WAY too wide. I'd like to find a Hudson Hornet or Packard to slide over that one. Might see if I can find an 80's Malibu 2dr for the VJ, that dash can be narrowed easily. I helped a guy do a '58 Studebaker Lark Pro-Street and he grafted the firewall and dash from a '80 Malibu Classic wagon in... Looked really cool and it allowed him to cut out all the Stude's rust.... Typical MN car, everything from the sill down was gone.
Think of it as a mountain climbing or storm surfing thing.... It's therapy, the pride of accomplishment, the 'wow' factor at shows.... Most of all, the joy of driving.
Happy trails.
