NOTE: This transmission support mount is designed around the
use of the Advance Adapter transmission to transfer case housings.
When used on Dana 300 transfer case kits, the original transmission
support and snubber can be eliminated. New holes will need to be drilled into the skid plate. Using the illustration
provided, bolt the structural tubing onto the bottom of the new adapter housing. We have included both 3/8" and
7/16" bolts depending on which model of transfer case adapter you are using. The neoprene insulators will need
to be pre-assembled and installed before bolting the tubing to the adapter housing. See illustration for the
installation onto the original skid plate or crossmember. We have found this mount to be a heavier design and
provide more stability than using the original Jeep transmission support. On Wrangler vehicles, we use a similar
kit, P/N 716008, that offers a wider stance.
On some installations that are not equipped with a body lift, it may be necessary to lower the transmission
support in order to obtain the necessary floor board to transmission clearance. It is not uncommon to use
spacers in between the skid plate and frame rails to achieve the proper crossmember height. If you would like
to raise your transmission closer to the floor board area, then we have had a few customers suggest a spacer
between the new mount and the bottom of the adapter housing. This spacer can usually be something similar
to the structural tubing that we are offering.
When using this mount on NV4500 transmissions, with the stock Dodge tailhousing. We offer a
additional spacer block to take up the added clearance between the adapter housing and the new
716021 mount. P/N 716048 is a 2"x 2" spacer.
SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to
any of the components will void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required
to complete your conversion, we strongly recommend that you contact our sales department for more information. This instruction sheet is only to be
used for the assembly of Advance Adapter components. We recommend that a service manual pertaining to your vehicle be obtained for specific torque
values, wiring diagrams and other related equipment. These manuals are normally available at automotive dealerships and parts stores.

NEW TRANSMISSION CROSSMEMBER SUPPORT
DANA 300 1980-86 VEHICLES
Please note:
NOTES:
1. Two (2) new holes will need to be drilled through the skid plate
for rubber mounts.
2. Smaller rubber mounts must be placed inside tubing before
inserting 5/8" bolt.
This mount (Part #716021), is designed for 1980-86 Jeeps
only. It has been designed around the use of Advance
Adapter transmission to transfer case housings.
The torque spec. will vary depending on the condition of the nyloc nut.
A new nyloc nut should be torqued
to 100 in./lbs. (approx 8 ft./lbs).
Visually, the supplied washer should
become "sunk" into the top of the
small rubber mount. Once the
washer "disappears slightly below
the rubber, you have reached a good
pre-load. Be aware that the tighter
the bolt is, the "harder" the rubber
will feel with power-train flex.
