Semi-monocoque chassis cleaned, prepped and coated with truck bed liner coating for sound deadening
100% Aluminum semi-monocoque chassis. "V" the local shop helper, puttin in a little time for a mock drivetrain assembly
Final Drivetrain fitment
Custom made slip yoke - U joint drive shafts..nice vintage look.
Spent a bit of time hunting through the Spicer catalog to find necessary pieces.
Max rebound (dropped suspension) with such short shafts was the big challenge,
as the angle was bottoming out the range of joint articulation.
Meticulously created wiring harnesses
- 6 Point roll cage
- 5 Point safety harnesses
- Wilwood 6 piston front and 4 piston rear brakes
- 2 piece NASCAR rotors with aluminum hubs
- Dual brake master cylinders
- Braided stainless steel brake hoses
- Stainless steel brake tubes
- Cabin and engine-bay fire suppression system
- Quick release steering wheel for easy ingress/egress
- Custom made telescopic/collapsible steering column
Full roll cage
Safecraft fire supression system, with both cabin and engine bay feeds.
Decided to fabricate an AC system... Needed to make a vent plenum for under the dash
So made a wood mold, and layed mat glass to make the vent system.
Here is the final product set in place.
Fabricated a set of brackets to mount the compressor
Body & Paint:
- Gulf style rear wheel flares and cut outs
- Meticulously prepared fiberglass body
- Exemplary body seem gaps and panel alignment
- DBC Base Coat / Clear Coat paint
- Body color masked for stripes, so NO paint rise at stripe
- Body panels painted body color & striped inside and out
- Hand wet sanded and rubbed
Panel prep work ongoing....
Wheel well flare prep and fitment
Flare shaped and fitted with initial glass bonding completed
Reinforced resin layer. Final filler layer completed.
Now the rockers needed to be flared to match the rear wheel arches. To do this, I created the desired shapes
using air drying modeling clay, glued plastic bag material to the clay to act as a release agent, and wrapped
the molds in mat fiber glass.
Initial fitment Installation: bonded and filler started
All painted and ready for assembly
Original style Dzus body fasteners and lights
Fabricated a radiator protector screen (not shown above)
Labor intensive utilization of hard lines throughout the build.
No cost or effort spared in the process of the build.
Car weighs in at 2450 lbs. Well balanced at 44% front / 56% rear.
( 8.11 lbs per H.P. )
Stripes were painstakingly painted next to primary body color.
This provided a smooth as glass finish, with no rise resulting from material build.

Arrows indicate new oil passages which were drilled.
Safety wired crown wheel (ring gear)
