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.
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. This is a complete kit which would include a new stub yoke (weld yoke) bearing cross and U-bolts.
