Hey guys, just following up. After a lot of digging through old boxes, I've found the vin as well as some other specs. According to the vin it's a 1946 Kb1 with a 213 Green Diamond. Thanks for all of you help!
With that being said, The motor maybe seized up. It's full of oil and will try to crank it this weekend. Planning for worst case scenario, does anyone have experience dropping another motor in this model? Is there anything that bolts in? I'm relying pretty heavily on this forum so any information you have would be great. Thanks again for the help!
