- 1979 CJ-7 with a fiberglass body and 1982 wide track axles, 258 I-6 with a 1995 4.0 head, HEI distributor, Motorcraft 2100 Carb, T-18 wide ratio tranny, Super Lift Springs and 33s, a 1997 BMW 328i, and a 2010 REDLINE CONQUEST TEAM Cyclocross Bike. :)
Ok, my new toy 79 CJ7 is finally on the road with tags. I just installed the speedometer cable and checked it against the GPS to find it's wayyyy off due to the 33" tires. It's only reading 40mph at 60.
Anyway, I was trying to look up a source for speedometer gears for the Dana 20 and ran across all kinds of conflicting info. One site said you can't even change the speedo gears in a Dana 20 but you can change them in an 81 or newer Dana 300 . Is this correct? If so, I guess I'll have to get an external adapter to screw in between the cable and Transfer Case .
I found other sites where people said you CAN change them in a 20 but I haven't found anyone that sells the gears.
For the record, I have a 1979 Dana 20 and 3.55 axle gears.
