Last year I extended my 1976 Bombi and put on a new style cab .This year I got an idea to swap out the 4 cylinder for a 200 ford industrial 6 out of a swather and an automatic trany .$500 later i had a swather motor and trany 81 ford C4 trany . I pulled the old motor cut out all the old mounts off fish plated the sides installed new mounts. I had to buy a reverse rotation fan and change the rad outlets other than that went well .ready for the test drive
