Look out for irate stovebolt owners with buckets of tar, feather pillows, pitchforks, and torches!

I would hazard a guess the axle width would be just a little narrow, and the wheelbase might be a bit short, depending on the model of Toyota you're considering. Try parking the Toyota beside your stovebolt, and doing a little eyeballing and measuring. Just about anything can be adapted with enough time, money and effort, but you might consider going with some of the more conventional retro-fits like an S-10 frame.
