I cut out the front suspension cover and shave the inside with rotary tool and used SMS PE set to test fit the inner surface. It took a lot of patience to thin the monocoque's surface.

Another view from the top.

I used 2 thin plastic strips to fill the edge on both sides of the opening because it is too close to the side surface of the monocoque.

Then, I puttied  the inner surface to get it smooth and prepared to attach the PE part.

This Gunze battery powered rotary tool is very handy. It helps to thin out surface without melting the plastic.

Now, you can see how thin the surface is compared to the original stock one. I sacrificed another kit to get the front suspension cover.

I covered the opening surrounding and white primer was spayed to check any imperfection.

Look ok so far.

Now I placed the cover from another kit into the opening, you can see how thick it is.

I used a rotary tool to thin out the cover.

Now it can sit nicely in the opening.

Then, I sanded off all the excessive primer from surrounding area. You can see there were cracks around the opening because the surface got sanded down too thin. I used CA glue to fill up inside to avoid it being cracked again.

I built a rack to hold the front suspension absorber and steering rack.

Front view of the rack.

Time to build front shock absorber. I took out  spare parts from my F1-2000 kit.

I used alum tube and brass rod to replace the middle section and kept both joint ends.

Here's how it looks like after the middle section was replaced. I used a plastic rod to keep track of the length so that it wouldn't be too long or too short.

I used white glue to glue up the absorber ends and brass rod and test fit it into the monocoque rack. It fits ok.

Here is the throttle/brake unit. Originally, I used one from  Studio 27 and a spare F310B rear absorber as hydraulic.

But it didn't look too good, so I switched to use the SMS one and then it looked very nice. The upper is from SMS and lower from Studio 27. I used some spare parts to make the throttle base.

They were I glued up and tested on the monocoque floor.

I used spare F310B parts to do the hydraulic unit behind the throttles.

I finalized the front absorber and misc. throttle units by applying CF (SMS one) onto alum tube. I used thin wire to make coil and hand brushed the joints and hydraulics..

Throttle and brake unit is done.

Since I needed to build the steering rods, I decided to use a spare F310B suspension arm to do that. According to reference, steering rod has 3 pieces.

I just cut the H-shape ends from suspension arm and glued it on a plastic rod.

After all inner details were prepared, I glued the monocoque bottom to the main monocoque and scratch built the bulk head face. I decided not to use Perfect Parts or SMS because I had shaved the inner surface very thin.. It's easier to use plastic sheet instead.

Another angle. Please note that front upper suspension arms needed to be cut off and fit into the monocoque first.. Be sure to use CA glue to seal the surface from inside. This is to ensure it has been securely attached and will not crack later on.

I scratch built a screw holes around the monocoque.

Do the same around the air box just to make it look more realistic.
