I have 3 frames available. The top frame is in the best condition.
If I remember correctly it is a Series I and I do have a title available. Let me know if you need more details.
Price of just the frame(NO Title) is $500.00 .
The L-4 engine came from a 1/2T commercial vehicle, sedan delivery I believe, and is a 3 speed. I will forward a current GP parts list to your email address.
