Looking good, Astro! Appreciate your keeping us updated.

Some more progress on the car. Made new inner body panels and mounts, these really soaked up a lot of time.
Fitted an new fuel tank, header tank and oil catch can.

I am making my own mufflers as I could not get commercially available ones to suit what I wanted. The main muffler body is 100mm by 1.5 wall, I had intended to machine the end caps from 1 billet but that was going to become expensive so I machined end cap rings from 100mm x 6mm wall tube, the rings were tapped m6 in 3 positions on each cap to allow me to disassemble to repack the mufflers. and made end plates from 3mm plate. The end cap socket I made from 50mm x 6mm wall, they were bored to fit the perforated tube on one end and an adaptor sleeve on the other end which will be welded to the exhaust tube. are all yet to be welded together. Just hope the sound is OK.

I decided to run the exhausts forward in the body exiting out the side of the undertray, this made the exhausts much easier to make rather than running them through the suspension links and out the back.
I have cut the original fibreglass bodywork to allow widening and am in the process of fitting all of that together with radiator ducts and new mounts.
OK, back to the shed for now.
