In the 24 years my 37 was apart it had not been touched for 10 years,my uncle who was helping me dies (self inflicted) so I lost interest and it just sat. After sitting those 10 years I figured out it would not get done by itself so I started back on it and 12 years later it was finally on the road,my problem was in those 12 years I was working on it I would find something else and work on it neglecting the 37 for awhile and when it was done start back on the 37 untill something else came along.
