Thanks guys,
More progress (Y)
Picked up the collar Monday night, seen here in situ

Took the dizzy to work Tuesday, guy that was meant to be doing it forgot to do it. Nevermind as SWMBO picked up the special order exhaust bends for me from the local factors. Came home all excited expecting to be building my inlet manifold only to find that they'd ordered the wrong size. Spent the evening in the garage rebuilding the garage computer instead.
Today was better, got the bends ordered through work, they'll be here tomorrow. :grinning: Guy at work did the dizzy :grinning:
My hybrid dizzy

Now all I needed to do was make the section for the dizzy to bolt to.
The spacer needs to be 20mm thick, I'd only got 10mm so 2 bits were welded together and angle grindered into the right shape, hole drilled for mounting bolt.

Welded onto the collar, welds smoothed, hole drilled and tapped to hold the dizzy into it, painted and fitted(Y)

Well pleased with that. Inlet manifold tomorrow (Y)
