It's not as simple as just finding and installing the bracket and a few bushings. There is a plethora of parts that make all of this up.
The bracket that goes from the exhaust pipe to the transmission is 108-492-03-19. Still available and very affordable.
The bushings actually came in a kit. It included the "U" shaped clamp, washers, spacers, bushings, etc. Part number 126-490-03-37. Unfortunately, that kit is no longer available, but the individual parts that make up the kit should still be available separately. This list of parts are as follows:
123-492-00-27 "U" shaped clamp
(2) 000-990-32-50 Copper nuts for "U" shaped clamp
( 8 ) 002093-016100 Washers for "U" shaped clamp copper nuts (4 on each side)
(4) 121-155-01-81 Eslatomer bushings
( 8 ) 000440-009103 Metal washers for elastomer bushings
(2) 126-492-00-76 Washers for between bracket and transmission
(2) 000931-008266 Screws for bracket, bushings, and washers through bracket and transmission bracket
(2) 126-492-01-72 Spacer tubes for in between bushings
(2) 304032-008005 Nuts for through screws
If that is too daunting for you then you can order kit 126-490-04-37, which is still available, but will include a few items you don't need.
You also seem to be missing a heat shield that goes between the transmission and where this exhaust bracket mounts to. It shields the modulator valve diaphragm from exhaust heat. See picture below. Part number is 111-492-04-30. It's no longer available, but the part number will be a good reference.
