    I came across what looks like a good deal but I haven't went to look at the truck. It's a 73 K5 that's an Auto and he say's it has the 205 in it. Must have been swapped in or something. Anyway, I was considering buying this vehicle for the X-case to eventually do the doubler. Who is running this in thier DD? What is the average cost to install one of these units? I have done some searchs and read tech articles, but Now I need some personal opinions. Thanks Guys and Gals. /forums/images/graemlins/ears.gif

    $2k including d-shafts

    The ORD doubler is a great setup!

    I haven't installed mine yet, but a tight budet number is $1500 but that is without driveshafts. I got lucky and can keep my rear shaft stock and I will lengthen my my front shaft myself.

    You may also get lucky like me and have your old rear shaft fit in the front. It was a 79K5 with a th350 and 203...then went to a sm465/203/gen1 doubler/205(for a th350). Worked out real slick and only had so buy a rear shaft.

    I spent about $2k on mine with shafts and some exhaust work.

    Mine is not a DD but there is no reason why ya couldnt drive every day with a Doubler /forums/images/graemlins/thumb.gif

    Most likely the trans is a th350. If so, you will have to have the input machined out for the bigger bearing. The th350 version 205 has a smaller bearing then the th400 205. It will probably be worth it to look for a th400 version rather then paying to have the other one modified.

    I have a doubler in my truck now and I like it. It was either the double or lower gears(when I had the 60 and the 14 bolt). They were both around $1300, but with the doubler you get to keep the highway gears and have 2 low range choices. /forums/images/graemlins/truck.gif

    I see no disadvantage of a doubler setup onroad, for me it will be an advantage over my current SM465/203 setup. I plan on triple sticking mine this way I can do whatever I want with the cases!
