SPECIAL INSTRUCTIONS:

This adapter kit is designed for exclusive use with a GM TH400 transmission. Since
this application is for a Ford Early Bronco Model 20 transfer case, you will need to
consider how to couple the TH400 to the Ford engine. We offer

P/N 712588

.

This kit is supplied with a new spud shaft, bearing, and seal. These components will
need to be installed into our alignment retainer, along with the stock Bronco Dana
drive gear. Make sure all snap rings are in place. Install the O-ring on the retainer
along with a small amount of R.T.V. Blue silicone, then install the retainer to your
transfer case. Bolt the adapter ring to the Dana 20 using the (6) S.H.C.S. bolts.
Rotate the spud shaft to check for proper installation.

When assembling the transmission to the transfer case,

DO NOT FORCE

the two

gear boxes together. If the shaft is too long, there is the possibility of pre-loading the transmission bearings, causing
premature failure. Take the extra time to make sure that the shafts do not bottom out internally. If there is any
interference problem, it may be necessary to grind the end of the new output shaft to obtain the proper length.

A shifter bracket has been provided for a "T" style T/C shifter handle. Before installing your transmission/transfer
case assembly in your vehicle, check the fit of this linkage bracket. The mounting hardware for the transfer case
linkage has been left out due to the various "T" style linkages being used.
