I am interested in the "granny low gear" version . Need pictures showing the gears and GM case numbers . Shipping to nearby Salem OR. Be kind to send me a pm . Thanks so much Martinius Berg
The SM420 was standard with a granny low gear. I am also in Oregon about 4-5 hours South of you. I have one, but it has been sitting outside for awhile. These are dime a dozen. In the Salem/Portland area there are tons of Junk yards so I bet you could easily find one close to you.
