Plan a 1978 Dodge D100 Lil Red Express DIY Build
The 1978 Dodge D100 Lil Red Express DIY Hot Wheels kit starts with a stripped pickup body that you can paint and reassemble. The photographed parts show why it is worth planning the truck as a whole before choosing wheels: the cab, bed insert, tall exhaust stacks and separate base all have to settle into place together. Its listed factory wheel reference is 10 mm at the front and 10 mm at the rear.
Start with the parts shown in the kit
The gallery lays out a bare-metal body, a base carrying the wheels, a window insert, and a separate interior and bed insert with the exhaust stacks. The assembled photograph shows how those pieces form the pickup. The shop notes that interior, window and original wheel colors may vary, so use the pictures to understand the parts and layout rather than to request a guaranteed color combination.
The casting has already been stripped for painting. Custom wheels are sold separately. Plan your paint, tools and any optional graphics around the finish you want; this is a painting and reassembly project, rather than a finished red truck.
Dry-fit the cab, bed and base before painting
Begin with a temporary assembly using the supplied parts. Check that the window insert sits inside the cab and that the interior and bed insert settle into the body without being forced. Then bring the base into place and look at the truck from the side and from above. The cab should sit squarely, and the bed insert should line up with the opening in the metal body.
The exhaust stacks rise above the bed beside the cab, so watch them while handling the insert. Hold the larger body of the part instead of using a stack as a handle. A dry fit also shows which surfaces will meet after painting. Keeping those mating areas clear of heavy paint buildup helps the parts return to the same position during final assembly.
Choose a compatible primer, color coat and clear coat for the materials you will finish. Follow those products' preparation, ventilation and curing directions. The kit's stripped condition removes the need to plan around an existing body color; it does not replace the preparation instructions for the paint system you choose.
Decide whether to keep the wheel setup or change it
The merchant-listed 10 mm front and rear reference describes the factory setup. It is a starting point for comparing replacement wheels, not a measured fit guarantee. Two wheels with the same outer diameter can differ in width, hub shape and axle spacing, which affects whether they clear this truck's fenders and base.
| Choice | What to check | Why it matters |
|---|---|---|
| Use the supplied wheel setup | Reassemble the truck temporarily and turn each wheel. | You can establish how the supplied parts sit before adding paint or changing the stance. |
| Fit a separate custom wheel set | Compare diameter, width, axle length, inner spacing and fender clearance. | A listed 10 mm diameter alone does not establish that a replacement will fit or roll freely. |
If you change the wheels, fit and check them before committing to final assembly. Turn them with the body and base together, because a wheel that spins on the bare base can still touch the body once the truck is closed. Browse replacement wheels and rubber tires after you have the measurements from your own kit.

Finish the truck without rushing the last fit check
The kit uses a click-together design. Muncle Mikes notes that model glue can provide extra hold, but first confirm that the pieces seat correctly on their own. If a joint will not close, look for an insert out of position or paint buildup before using adhesive to hold it under pressure. Use an adhesive suitable for the actual materials and follow its instructions.
Let your chosen finish cure as directed before handling the body for reassembly. Compare the result with your earlier dry fit, and turn each wheel again. That gives you a clear point to catch a rub or a misplaced insert before treating the build as finished.
D100 kit questions
Does 1978 mean this Hot Wheels toy was made in 1978?
No. It identifies the vehicle model in the kit name. It is not a verified manufacturing or release year for this particular toy.
Are custom rubber-tire wheels included?
The current kit listing says custom wheels are sold separately. The gallery shows the supplied rolling base; wheel and component colors may vary.
Will every 10 mm wheel fit?
No fit is guaranteed by diameter alone. Check width, axle dimensions, inner spacing and clearance on the actual truck, then test the assembled fit.
Is the kit already painted?
The body is stripped and prepared for your paint and detailing choices. The bare-metal photos show the starting project.
