Guys, need some help. Couldn't find info by searching the forum.
I previously posted my challenges in trying to pass smog with my '89 964 3.6 conversion but I am really close to passing and have narrowed the issue down to leaks in the exhaust due to the slip on collectors for the headers.
I am now trying to make a jig to weld and seal my header pipes with a 3-1 collector and would like to confirm the vertical and horizontal (x and y) dimensions between the holes of the
individual header flanges as shown in sketch below.
I measured with scale but not certain if the set up was square so I'm hoping someone has the specs.
I appreciate any information you could provide.
Thanks in advance.
