Like everyone said, get one of the associated ones for about ten bucks.......The weight of the ones you get at the track is about 0.7 oz.....1/2inch high...and 1and1/4inches long......the AMB transponder is so small and light that making a fake one would serve little purpose for car setup,besides if you own one you wouldn't need a fake one right

Also if none of the tracks you race at use them what exactly would the use of having a fake or even a real one??? They don't work with the old system......

Also to the origional poster on this thread, if your LHS refuses to get/sell them it's probably because they don't use them either.....

Thanks for the replys

I have access to a CNC machine as well as whatever metal stock I want. Its no more of a matter of plugging in the correct numbers and having the machine create the fake transponder for me.

Since this what I do for a living, its not a matter of $10 vs something I can easily do.

I can also take my digital calipers to the track as well as a digital scale and measure everything when I race Sunday -- I was hoping someone had the dimensions and could save me the trouble.

None the less, thank you for all your replies
