i am working on a Wheely King project.... and have another that i am about to start... and i see everyone changing drive axles and i have plan to do the same with a revo shaft. however....i remember purchasing the ground pounder aluminum shafts for a GP i had....and i was curious to know if these shafts would fit on the wheely king. they were as tuff as nails....and if i could find out if the shaft would be long enuff for the wheely king and the hole saize diameter close with the crawler conversion it would be a big help......
