I am half way,money-wise to 6.1 conversion for my 87 GN. My question is: What if I buy what I can now and the car wont be drivable, (Mi weather) until March or April what kind of warranty/quality does a Scanmaster/wideband have sitting until spring? No disrespect to any vender/manufacturer intended, but I never had very good "luck". Should I wait to buy when I can afford to order all same day/in the spring?Mark.
