Some people are like Slinkies. Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs

You'll have to get a new output shaft and an adapter for the 205 tho.

seen alot of them split in 1/2

FWIW cast iron doesnt like being streatched.

im running a 203 currently. the biggest problem i have was the linakge came loose and would pop out of 4H/L lock and into open. and ahad interferance with the floor board.
