How much will it cost (est.) to switch from an auto to a 6sp tranny?
 

I was planning on having my auto tranny (700r4) rebuilt with a shift kit and vette servo, but I was wondering about how much will it cost to switch to a 6sp tranny, with labor and all conversion pieces. Also will it be worth buying a used 6sp tran from a 4th gen?

Thanks for all responses
