OP the toolman ChatMaster - 2,000 Joined: Dec 2001 Posts: 2,037 Likes: 5 Canton, OH	I have included a picture of an unknown differential side gear. Beside the unknown gear is a 1939-1942 Chevy differential side gear - part # 3651053. The overall diameter is 3 5/16". The unknown differential side gear is 3 1/2 inch in overall diameter. Any ideas what year(s) this gear fits? Is it a 1946 - 1947 - 1948 ish gear ?

The unknown gear is unmarked. dave the toolman 60th Anniversary Meet Chairperson Dave VCCA # L 28873 VCCA #83 Tool Technical Advisor for 1914-1966 VCCA #83 1940 Chevrolet Technical Advisor
