It’s been a while, but finally another update.
Some time ago I dressed back the welds on the heater plenum panel, but as I’d butt welded the infill panel and there was a fair amount of heat distortion after welding, the panel became quite thin in places resulting in a few hairline cracks. Oh well, live and learn! [:I]
Given that I had some “reshaping” planned for the heater plenum area anyway, I decided to cut the whole lot out and re-weld it on the bench, this time overlapping the panels and welding on both sides.


Once I was happy with it I tacked it back in place, but because I’d also shortened it up and altered the mounting angle to suit my slimline heater bubble (see page 3 in this thread), the surrounding panels in the engine bay also needed to be altered and more infill panels welded in place. It’s looking like the changes will provide another two to three inches of space over standard.




Once I’ve finished the plenum area, the gearbox tunnel will need to be moved back and then I can weld in a new recessed panel under the plenum. It’s probably a lot of work for not a huge gain, but it’s all part of the challenge and maintaining the heater bubble to keep it looking “right” has been the number one priority.
So that’s about it for the moment, however last night I couldn’t help myself and trial fitted the front panel, front guards and steel rear bubbles...
