lightweight sleeper build

Post by coomo »

Apologies to mods (Bootsy) He must wonder what im doing,editing and deleting threads.Fact is,I struggle with computer stuff,and its taken me few hours to reach a point where I can do this,without too much grief. :oops:

I drove this 1978SC back from the coast of Sctoland 5 years ago.It had been previously backdated,many years before.The standard on the work was, well sub.I knew it would require tearing apart.The first clue was when I was sitting in my chair,drinking tea.I looked down and saw the sidelight/wing gap!

After a few weeks, strip down was complete,and a full survey of required work,could be roughly asessed.Then,I began my least favourite job.Removing the underseal prior to shot blasting.The most efficient way is a map torch heavy gloves, full mask and various scrappers.Its no suprise they rot.Up into the rear light fitting,its solid seal.No -where for water to escape.

underside was pretty good.No corrosion to floor pan, which was nice.Rear rails required some attention,under tube rail thingy place.
Image

Image

Image

Heater valve locating studs.Heres a top tip.If they are rotted out.Grind out the remains of the old studs.Then you can drop in a bolt,and let a flood of braze in,to well braze it.
Image
Area under rear sway mount.
Image

Spun over, onto Jig, Rear quarters removed.Inner.outer sills etc etc.

Roof panel cut.All rain channels removed, and outlets welded up.
Image

Image
Image
Before roof panel installed.Remove glove box and fab a panel.
Image

Image

Carbon roof panel (1.5lbs) If your considering a sunroof delete,you may find this a more economical option.Not sure how much the steel delete panels are now.Chris at Fenn Lane used to sell for £150ish.Obviously thats now not an option.The carbon panels i get from neville at F1motorshop.(£800ish)However, to weld,and fit a steel delete panel,is a good few days work.Plus you need to be able to acess welding gear etc.Once the roof is cut, the carbon panel can be fitted in under an hour,Far more simply, with much less refinishing.You just need a lot of clamps!

Rear seats are not an option.Nor Am I keen on the rear carpeted look.Instead the interior, will be a paint finish.However, the rear tub, is deep
and wide! I fabed up some panels backed with soundproofing, and welded in.They will take a very slim cushion if required.lots of filling to smooth it all out

A central mount for an extinguisher
Image
Image
I had a genuine "matter"alloy cage from the 70s, that was in a race car.It fiited well.Off to Custom cages, to scan and make me a steel copy.

Image
Doors were in great order.I hand strip,then send off to blasters to clean edges and interiors.

2 genuine Porsche front wings.As usual required fitting.Gaps to doors was way off.Welded TIG wire to wing edge.Then finished with lead to create decent gaps.
Image
Image
Image

Same for light boxes,and edge of bonnet.I used genuine 1970s grilles,and then leaded the wing edges,to create nice lines,and even gap with bonnet.

Will be using 911R rear lights.obviously being fibreglass,there is no real way to
fit these nicely.Again some lead in rear quarters to get nice fitment.
Image
Next step was to add chassis strengthening.Really a case of why not.Its not spendy, just time consuming,which for me isnt too much of a problem.Also if some lunatic in the future decides they want to go racing in it, or add ludicrous power.Well its helpful.
Rear tube plates.Courtesy of Elephant Racing.In fact these are quiet spendy! You do get a plate to help with warping and a nice box though.
Image
Image
Stitch welded front tub and you can just seen strengthening plates for through body sway bar.Really nice penetration with those welds,unfortunately the expoxy is flammable.Got kinda messy.Note to self: Stitch weld THEN epoxy!
Image
Top mount plates.
Image
front brace mounts.
