Update - My initial plan was to attach the bottom half of the monococque after painting was complete, but this would result in a fairly noticeable gap. The bottom half of the monococque had been primed and painted with TS47 Chrome Yellow from my first attempt. I have decided to go nuts with masking tape and just sand and fill this seam despite the fact that the bottom half of the monococque houses the cockpit and seat assembly. If I get over spray inside the cockpit I will not be a happy camper!
The "floorpan" has had some BMF applied to the heat shielding portions while the brakes and rear uprights have been applied. Note the lack of bodywork protruding between the rear suspension arms. I plan to go the crazy route and somehow weave them through the suspension arms once the engine is in place. I've already test fit them so I know it shouldn't be a problem.
