Necessary sheet metal modifications:
To maintain the original external appearance of the vehicle and allow for ample cooling capacity the “breakfast” or headlight
panel will need to be modified. The original radiator will not be adequate to keep the replacement engine cool. To make room
for a larger radiator the original radiator support structure needs to be removed. The original radiator overhangs the first cross
member.
The panel is easily modified. Drill through the spot welds and gently lever the two pieces apart. To maintain structural rigidity,
you can use three pieces of 1/8"X 1" flat bar stock. One across the top, spanning the width of the panel, and the two remaining
pieces will be welded vertically and parallel to the center opening. The latch is no longer used.
You will need to purchase military hood latches. This provides the space for a radiator on
top of the first cross member.
It is advisable to convert to power steering. When converting to power steering, the steering
relay is removed.
To provide room for a “V” type engine and maintain the original look of the vehicle
It is necessary to widen the firewall or “bulkhead” to accept the wider engine. This is easily
done by drilling out the spot welds that hold the center panel to the foot well. Remove the
panels individually and save them for reuse. Drill out the spot-welds of the inner kick panel.
The goal is to match to foot well dimensions to the driver side (LHD). Essentially creating
a large factory appearing opening. Fabricate a new center panel keeping in mind the bell
housing size, depending upon engine, transmission and placement .
