How thick is the cross bar that Dave has supplied?

I'll measure it when I'm home later.

I've had the same thoughts, I came up with rotating the inlet 180˚, core plugging the heater matrix feed, cutting off the 90˚ bend and having the straight bit left behind machined to fit a 32mm hose. If you make one let me know so you can make me one too. The small 8mm outlet can be cut and redirected using standard plumbing items or just blanked off.

Simply: No. They don't meet the requirements of either being attached at both ends or down one side.

Threaded bushes should be welded (at both ends) through the tube, and not end mounted on the surface. (A threaded bush may be attached by
its side surface to a structural component).

Here's what I did:

Use a piece of thick walled (3mm) square tube for the cross member and weld the bush to the rear side of that. I passed IVA ok that way. Tubing will also pass a radius test no problem.



Or weld the bushes through the round tubing supplied.

Hey guys, thanks for all the feedback.

Re the harness mounts I think I'll put them inside the cross tube (I understand I may need a new tube, I'll measure in a sec). Is their position ok?

Yes!i was having similar ideas but was sure how I'd machine the end. I was leaning towards making a jig to mount it on a lathe...

I was thinking of keeping the heater hard pipe though and running it to the heater outlet on the reroute spacer so there is still circulation before the thermostat is open.



Might need restricting a bit though or, it could be useful for a water cooled turbo?

The tube is 33.5mm thick.

Great minds think a like! Agree with all the above.:)

Well, I'll have a go with the one on the car and if that works ill do the same with my spare for you.
