149 engine pipe to manifold flange

Looking for two 149 manifold to engine pipe flange plates. These suit a 1 3/4” pipe and 2 3/4” stud spacing, same as X2 S XU1 headers, which I’m fitting to my FB ute.
Cheers

Apparently the stud centres are actually 2 7/8” for what it’s worth. And the pipe hole is originally
1 7/8”.
I got this information from Brad Merrick’s site https://www.xu-1.com.au/ and thought I’d record it here.

179 and 149 were the same. 1 3/4” engine pipe and I believe 2 7/8” stud spacing.

Anyone got an old EH HD original engine pipe flange they don’t need? 149 or 179, doesn’t matter.
