Has anyone used Redline Offroad for parts, axles, etc. I would appreciate any info - this will help determine if I am to do businesswith them. Thanks!.

I have not - but saw a thread or two on this BB about them. You might try doing a search on "Redline" and see what comes up. Also, there were threads on the Toy Truck section - definately ask there, and put the name Redline in the title of the post. Good Luck!
