You are buying 2 used Clark transfer cases for what I was told are for the Michigan Loaders Model 55 / 75. The models of the Clarks are T75-A3 and T76-B3. I looked inside and there was a little surface rust on some of the gears, but the gear teeth looked good to very good for what I could see. Sold "as is, for parts or rebuilding". Shipping is 1600 pounds truck freight at buyer's expense. I can get you freight quotes. Ohio buyers have to pay 6.5% sales tax.
