theres only 2 other conversions i have seen  chris grompixs T34 with i believe are tammy boxes in and perrys on Cough RCU who squeezed a set of h/long boxes in but had to make a bulge in the rear to accomodate them 
 
 
this conversion if you havent got a spare set of metal h/long drive shafts will cost about £60
£43.50 for the low profiles £9 for the wsn upgrade gears and £10-£15 for a set of metal H/long gears
My T34 is already complete this one is for Dragon245 ;)for dragons im building a complete new floor out of ally so the tank wont flex anymore but SSHHH he doesnt now that yet
