Exactly what I intend on doing. I found a Super C with a good block and rear rims and hubs which my 200 needs, as well as a drawbar and narrow front with good tires. good sheetmetal. I think i will build it with the crank, rods and head from the 200 as well as govenor and such. I have a SC already and it is the high alitiude pistons in it, F/H and good rubber all the way around.
