I am in need of some experienced Sprint car knowledge. I bought a large lot of Vintage Dragster components and ended up with some Sprint car drive line items that I have no idea what they are worth since I am not well versed in that type of race car. I have included an image of these items that I will describe as shown. On the left is a Jones magnesium 11 bolt housing stamped # 61247 On the right is an aluminum Franklin 11 bolt housing that will need finishing machine work Bottom left to right is a steel 31 spline spool A large steel bearing race collar A Winters Performance magnesium rear cover with bearings stamped # 5017 A steel 7 tooth spline pinion shaft # 21-5089 7 3/4 A steel 34 tooth ring gear # 2K 5090LR 7' 34A And a steel 10 spline lower shaft Any and all input will be appreciated. Thank You and Happy New Year!
