I just got a SM420, 7.05:1 first[img]/wwwthreads_images/icons/smile.gif[/img] and am thinking about different transfercases with the front driveshaft on the drivers side. anyone know if there is an adapter to mate a "Chevy SM420 to and Ford Dana 20"?
Don't the ford 20 have a 2.4:1[img]/wwwthreads_images/icons/smile.gif[/img] low range also?
The bolt patterns are the same for all Dana 20's but the spline count on the input shaft is what varies from Bronc's to Scout to Jeeps. I think Advanced adapters can put almost anyD20 to your tranny advancedadapters.com. And yes Bronco 20's have 2.46:1 low ratios same as a Dana 18.
