This is old stock original part. It is new never put in a car. For Studebaker high performance engines 389 & 302. Made in the USA. A-899-3 Aetna Ball & Roller Bearing Co. My Dad rebuilt Studebakers for fun and was a member of Amarillo Studebaker Club. He wanted
to rebuilt an Avanti but never found one. He went to shows and conventions which is where he purchased this. He loved his Studebakers. He purchased this in 1970's and took very good care of it until he passed at 94 in 2021. This is a rare part.
