I'm changing to a t5 and have someone wanting my c4, it functions fine, just needs flywheel replaced because of some missing teeth, other than that it's complete... He either wants to buy it or trade fair really a 4 speed out of his 66 six cylinder...should I trade and try to sell the 4 speed or sell mine straight up? Not really interested in the 4 speed since I already have the t5 but if it's more valuable than the c4 I might trade... So what's each of them worth?
