DIFFERENT DONOR VEHICLE OPTIONS
We highly recommend NOT using these different donor cars for the average build. This list will help
with those parting out individual items, and possibly for those not using all of the donor parts.
1982-1986 8 Donors
• Front brakes are 10" in diameter compared to the 87-93 11" diameter.
• Gauges will not work.
• Transmission is slightly weaker, and 82 and most 83's used a 4-speed called the SROD that will
not work
• Rear axle has a 7.5" ring gear, so it is weaker (86-93 axles have the 8.8" rear axle)(the 7.5" rear
also did not use quad shocks)
• Engines were carbureted up until and including 1985.
• Front Spindles will work by cutting the weld tacks and removing spacers on the IFS brackets that
come with the kit.
• 1986 donor vehicles were fuel injected, though they were less powerful, and they had domed
pistons that make performance modifications difficult.
• 1985 and 1986 V8's with automatic transmissions, were throttle body injected.
1982-1993 4 Cylinder Donors
• Front brakes are 10" in diameter compared to the 87-93 11" diameter.
• Rear drum brakes are 9" in diameter compared to the 87-93 10" diameter.
• Gauges will not work.
• Transmission is much weaker. The input shaft is smaller, so a different pilot bearing would be
needed. It also has a lower first gear.
• Rear axle has a 7.5" ring gear, so it is weaker.
• Front Spindles will work by cutting the weld tacks and removing spacers on the IFS brackets that
come with the kit.
• Fuel pump will not support a fuel injected V8.
• Engine section of the harness will not work.
• Steering rack has a 20:1 ratio compared to the V8 model 15:1 steering racks.
• Radiator is only a single core.
1994-1995 Donors
• These two years use a mixture of the older 87-93 parts and the newer 4.6L parts.
• Front spindles are 5 lug and can be used with 13" "COBRA" Brakes.
• The 1994-1998 rear axle is 1.5" wider than the older cars and must be taken into account when
ordering wheels.
• If running emissions and catalytic converters, it is necessary to switch the front accessories,
mounts and water pump with the ones from a 1993 or older car because the air pump will hit the
catalytic converter.
