The only machining required will be four mounting holes drilled into the fiberglass floor area of the oil cooler opening. There a few different options to choose from. Lights or no lights and polished or unpolished. The no light option simply has a full width grill to fit the opening, same materials only wider horizontals. An unpolished kit is for those that wish to paint the horizontals.

The lights are a quality set with alloy housings and glass lenses. They come with a fused wiring harness, relay and double throw rocker switch. The lights are very bright 55 watt halogen bulbs which are replaceable. These lights also have the benefit of being a dual bulb unit. Each light has an auxiliary blue 5 watt "parking" lamp. This can be used as is or swapped out for a clear wedge base bulb and use the lights a DRL's or Daytime Running Lights. Jump to purchase.
The lights and grill are a very good proportional fit to the opening and compliment the exposed radiator. Mounting hardware and internals can be painted black (which they are not here) as to hide the hardware. There is substantial mounting hardware behind what's seen which means there is little, if any, opportunity to mount an oil cooler behind. Many car don't have or need one anyway. The kit can be installed at any stage of construction or after. This is a cool kit for guys that may be finished with their cars and looking for something new to add. Jump to purchase.
All the fabricated parts are aluminum and all of the supplied hardware is stainless steel. The glass on the bulbs has an apparent blue hue but the light coming from them is bright white. Most of the blue of the lenses comes from the blue parking light bulbs, if you don't want or like them they change out easily. Jump to purchase.

Parts Prep – (recommended) To minimize the visibility of the mounting hardware, parts should be painted black - rattle can flat or gloss is fine. Clean these parts with alcohol or degreaser, spray and give time to dry. • 2x2x17-1/2” Aluminum Mounting angle • 2- Aluminum elbows for attaching grill to mounting angle • 8 pcs Aluminum Unthreaded Round Spacer 1/4x1/4” #8 Screw Size
Car Prep – Remove the lower aluminum panel from in front of the radiator. If this can’t be removed then all work will have to be done from underneath, which will make an easy job not so easy. Placing the front of the car on jackstands and having the radiator aluminum off is the easiest of all. Protect your paint around the nose opening with a layer or two of blue painters tape.
Light Prep – (consider) The supplied lights have two 5 watt “blue” wedge base bulbs as auxiliary parking lights. You may want to consider changing these bulbs to clear lights to allow you to use the assembly as DRLs or daytime running lamps. It’s easiest to do this at this stage.
Grill Assembly – (use the drawing as a guide) You should find six pieces of aluminum 1/8x1”, there will be two lengths of each size. The smallest two are center followed by the middle size and finally the largest. (Note: If your kit is full width then the slats are longer and assembled opposite.) One of the longer slats is countersunk for the oval headed screws, this is the top of the grill assembly. Insert the two screws through this, then a spacer, another slat, another spacer, another slat then the end of the mounting arm. The process is continued in reverse until all parts are used. Snug the 8/32 locknut up enough to allow for some adjustment. This screw will need to be trimmed off using either small cutoff wheel or grinder. If you leave it long for now, place some tape on the ends for protection of paint.
Assemble the grill arm to the mounting angle as shown on the plans using the 1/4x20x1” bolts, lock washers and nuts.
Light Assembly – Unpack the lights and attach the brackets as shown on the plans using the bolts from the light hardware pack. Then attach the lights to the mounting angle as shown using the 10/32 bolts, small fender washers, lock washers and nuts. The lights are mounted with the small bulbs outboard. All of these connections should be loose enough to allow adjustment at this point.
Car Installation - Carefully place the assembly into the oil cooler opening and adjust for preferred look. This may be a little awkward to do because the fiberglass floor is bowed upward in the middle. Take your time and get the best placement you can of the assembly, front to back and side to side. There should be room for final adjustments after attachment. Mark the two outside mounting holes in the bottom of mounting angle. I recommend a final hole size of ½”. The best bit to use for this operation is a step drill, this makes a very nice hole and will not grab or splinter the glass. If you have to enlarge a hole these are extremely handy to have.
Test mount the assembly to the car using the button head bolts and large fender washers from coming up from under the car. You should have enough adjustment in everything to get the lights even from side to side, rotate them to the correct angle and, have the lights spaced away from the grill evenly. Once you get it like you like it then mark and drill the remaining two center mounting holes in the body. Now move on to wiring.
Wiring – Follow the wiring instruction supplied with the lights. Depending on your configuration, and state of completion, it may be easiest to pick up power at the starter. The wiring harness has it’s own fuse for protection. Use the supplied mounting hardware to secure the harness for your chosen path. Be mindful of suspension movement and interference. Once you get the wiring all buttoned up and the lights working place the car on a level area to adjust the lights. Get the farthest beam and most symmetrical lighting you can.
After you’ve finished aligning everything, make sure all of the hardware is tight and the harness is secure. Reassemble the car and enjoy your new modification.
