I have a 1956 220a with engine number 180.921.6502914. The crank in the engine is part number 1800310801 with other numbers 37CR4 and A906/6. This crank has been cut to the limit previously and may need more now due to one bad rod journal. Rather than welding, I do have access to another crank with part number R1800311401 with other numbers CK45 A906/24 which looks like it came from a 60s 220s or 250. Anyone know if I could use this 2nd crank in my 220a?
