My Midas was originally put together with little or no regard to fit and finish - no surprise, it being an 80s kit car, but I am doing my best to bring up to some form of standard. The current problem I have is the dash top - the one that came with the car was completely the wrong shape and wasn't actually properly attached to the vehicle when I bought it - in fact it was just sort of laid on there. I do not have plans to use it, as it would take more work to make that fit than actually making something new. It is not part of a dashboard I can buy, I have used a template and a mould to make something last year but it's full of dips, it curves in all the wrong places and is effectively twisted, plus I gave no thought to how it would actually attach to the dashboard and car. It's a non-starter to use this one. A waste of time, fibreglass and effort. As you can see from the photos below I am starting from a blank canvas - I am thinking that I make a flat card template, then laying a basic flat fibreglass layer, using that as a mould to keep the dash top flat, and then somehow incorporating some brackets behind the main dash area (possibly in 4 points) to attach the top bit. I will need to incorporate the vents for the screen somehow as well. I am completely open to suggestions on fixings, coverings etc. I am possibly thinking a thin layer of foam followed by some vinyl or simply spraying the dash top with the textured paint I have been using to match the dash itself. I am struggling to think of an easy-ish way to do it, so all ideas and guidance considered. My thanks in advance! The big hole I need to fill. Wiring will be tidied up - it's just "there" at the moment. Sides - nothing to mount to.

Never done anything like this, but since the sides are fibreglass can you ‘glass in some aluminium brackets (or wood?) to give yourself some mounting points?

That would certainly be something I can do. Any suggestions on types of fixings always gratefully received. I want to be able to remove the top relatively easily in case of need. Also, with regards to shaping the dash, I am wondering whether sculpting some expanding foam could be a way forward?

I think you can buy big blocks of styrofoam cheaply. You could buy the necessary blocks, glue together if necessary, shape it nicely a tiny bit undersize, and then lay fibreglass over the top of it. I would think you'd need epoxy resin otherwise it'll disappear before your eyes. You might have to be careful not to accidentally snap the foam in half during sanding. On the plus side, it sands down rapidly. This is basically how surfboards are made. You don't even need to remove the foam if you fully encase it.
It also looks like a completely flat dashtop could work so maybe just a 5mm sheet of aluminium shaped accordingly?
Are there no air vents to consider?
Was this in the PPC mag this month? I thought yours was green.

I thought yours was green. It was in PPC yes - mine is most definitely VERY orange! It's never been green - apart from a bit of moss so I don't know where that's come from! Styrofoam blacks sound like a good plan. Air vents to vent the screen will need to go in.

I think I’d have a go with some mdf. Easily worked, wear a mask. Will take screws or through bolts. Layer of thin foam and vinyl over it and staples/glued to the back.
Edit. I’ve done a couple of rear shelves in saloons in the same manner to mount speakers decently after they’d been hacked at by previous owners

Worth bearing in mind that the windscreen seal will occupy some of that space, so you'll need to leave clearance for it

Black is not a colour ! .... Its the absence of colour

I did almost exactly the same. I made my template from 9 mm mdf, then laminated up the dash top to about 3 mm thick. I put "T bolts" in where required then layered up another 3mm. Ithe finished dash ( I've still to cover it in vinyl ) will be dropped in place, then nuts onto the easily accessible T bolt threads sticking down. For the screen vents, I fastened the vents solidly to the body after I had put rivnuts at each end. This means that the dashttop goes in place, then the outer trim pieces screw down through the dash top into the rivnuts on the vent. Hope this makes sense ! I don't have any photos at the moment

Use "trimbond"https://www.ebay.co.uk/i/151206875665?chn=ps&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=151206875665&targetid=1065995240397&device=c&mktype=pla&googleloc=9045696&poi=&campaignid=10204071591&mkgroupid=104953044434&rlsatarget=aud-629407026665:pla-1065995240397&abcId=1145987&merchantid=101717442&gclid=Cj0KCQiAtqL-BRC0ARIsAF4K3WHXFmso9SIGQpGJj2nLrMlLLC1A3C8vkjq4x2eByOhzfT_tr824hYwaAg9iEALw_wcB and 1.5mm thick card layer upon layer to create the desired shape ,either use as is or use as a template for GRP . Cover in high density foam 6mm thick and the a layer of vinyl. It can be held in place with brackets and door panel clips www.bresco.com/acatalog/Spring-clip-used-with-BSF087P.-Rover--Rolls-Royce-and-Bentley--and-general-application.-BSF316P.html#SID=23 For the air vent cut holes and fit over with vents from any model of car you think is suitable

I made a humped motorcycle seat but the method would probably work here too. Flat base, covered in expanding foam. Shaped that then covered it in chop strand fiberglass filler, shaped that, then covered it in foam backed vinyl.
