First off I am building a -7 with an IO-360. On drawing OP-33 Detail A shows a support clamp on the heater Scat duct. It shows it being SS 304 26 ga. 1/2 X 9". Is this a part that comes with the kit or something that needs to be fabricated? If it is something I have to make I think I would rather use a DG 33 cushion clamp because I do not have any 26 ga stainless. Is this a problem?
Thanks in advance!

A couple pieces of 1/2x9 stainless came with the firewall forward kit. I used them but still wonder why I didn't use Adel clamps.

I made some from some stainless strap left over from exhaust hanger work. Just about anything will work.
