Thanks for all the replies. I think I may just get one boxer motor and one gm9330 from ranch design so I can see which I like better. I may have to wait on the wheels that's out of my play budget at the moment. Thanks I got out the micrometer earlier to see what the axle size was.
I never thought spending 5 bucks at a garage sale would bring the little kid out in me lol I am officially slot car crazy.
Again thanks for the help I am sure I will have more questions but I really appreciate the help so far.
