The FJ80 Automatic to pre-1986 GM V8 Kit part no. 712535-C
 
This Mark’s 4wd kit utilizes the Toyota bellhousing, instead of a replacement bellhousing, a flywheel housing is supplied which measures 74 mm/2.9" long. This housing has the GM bolt pattern on the front and the Toyota FJ, bellhousing bolt pattern on the rear. NOTE: This kit does not use the original Toyota sandwich plate.
 
The transmission torque converter is coupled to the flywheel via a crankshaft adaptor. The adaptor has a special bolt pattern and spigot diameter on the transmission end with the GM crankshaft bolt pattern and spigot diameter on the engine end.
This allows the new flex plate (supplied in the kit) and the Toyota torque converter to be bolted to the rear as with the old 3F engine. On the rear of the engine the GM flywheel is used instead of a flex plate, as there is no provision to support a flex plate when the starter motor is engaged.
 
When fitting a Chevy engine you must make sure that the GM starter motor you intend using is the correct type. Chevy V8 engines were released with two flywheel sizes; they where 153 tooth ring gear or 168 tooth ring gear, as a result two starter motor offsets are available.
 
It will also be necessary to identify the year of the engine, after 1986 the engine crankshaft bolt pattern changed. The bolt pattern is smaller as is the spigot (52.4-mm), which locates the flywheel on the crankshaft. The post 1986 Chevy small block engines are also externally balanced. One way to identify a late model Chevy engine is by the one-piece external, rear main oil seal.
 
The Kit consists of: Adaptor flywheel housing, adaptor boss, flex plate, adaptor housing cover plate, all required bolts, oil pressure sender adaptor, temperature sender adaptor, instructions.
