FRONT YOKE & DRIVESHAFT CLEARANCE: On most transmission

swaps, we try to allow for proper front yoke clearance. However, the early Dana 18

transfer cases can present a problem. The Dana 18 transfer front yoke protrudes out

further than that of a Dana 20. Although front yoke clearance can sometimes be a

problem on the Dana 20, it is usually on the early Dana 18 transfer cases with the large

diameter yoke only that front yoke clearance issues are found. The large diameter yokes on most 1965 and earlier Jeeps will normally

interfere with the transmission pan on most automatic transmissions. This yoke has been discontinued; however, we have had

it reproduced. Our P/N 716407 is the same as the 1966 to 1971 small Jeep yoke.

All Dana 18 & 20 applications will require the centerline of the drivetrain to be offset 1” to the driver’s side. In many cases, you will

be limited on your driveshaft diameter. We offer a complete kit which would include a new stub yoke (weld yoke) bearing cross

and U-bolts. This kit also includes the new front transfer case yoke listed above. The complete kit is under P/N 716009.

TRANSFER CASE SHIFTERS: The 1941 to 1979 transfer cases use several designs of shifters. Illustrated below are the

various designs. These shifters are always supported off the front of the stock transfer case. On some of the truck 4 speed adapters

and the NV4500 adapters, you may need to modify your stock shifter. The instruction sheets provided with the kits will give you this

information.
