Hey dodge626, give me a call or drop me an e-mail, I"ve got the parts you need for your project...kingoftow 518 528 1668...vinsonbikeman7@aol.com

 

if your going to get the k-member and the motor mounts try and get a set of disc brakes for the front as well. if your going to do the conversion to a 360 your going to need some better stopping power.
