New price 9-5-05: $100 for the pair.....come get them now! Pulling them out of my '78 SBW K10. The tranny is the thick K-case 6 bolt dust cover type. 203 has been converted to part time. I will separate the two and I will separate the chain box from the range box for Doubler use. The 350 tranny has a slow park-to-reverse kick in but everything else shifts good, crisp and firm. New price: $150 for the pair. You come pick up at my place. You have your choice of getting the adaptor with the range box if you need the Doubler parts.
