i am building a speedway sedan . my starter car is a ae 102 hatch hit in the front. requires left corner cut, however i can buy half cut ae111 with a black top 4age all good.. my question is are the floor pans, rails etc., going to match up? these cars have a total nascar roll cage supporting the body so i am not concerned with reguards the weakening effect of half cutting. also is the black top a better engine performance wise over the silver top, we can run either? i hope some one may be able to shed some light on the subject . this is a step into another zone of dirt track racing front wheel drive for me.thanks. :dance:
