Looking to install a wedge adapter plate to install between my Gill manifolds and risers to add a O2 sensor. The bolt patern is 4.25" x 4.25". Havent been able to locate any?

did you talk to jeff wagner, IE, wags 362 in ohio? https://www.mapquest.com/us/ohio/wag...ring-550616801

No I forgot who you said when we were together. Thanks, Ill try and get in contact with him.

Not able to find any current contact information. Listed phone number no longer available, and dont see any further links.

I had no luck finding any either. Ended up putting a bung in the riser at a local shop for less than $300

txt me tommorrow , I have his number

Tbanzer,

How about this....?

Thanks. Brad.

That won't fit Gil/Merc risers.

I made my own on a manual milling machine and lathe. Anybody local with a small machine shop should be able to do it for you.

Donzi,

If this was in response to my post, it does mention "If you don't see your application listed, call". I'm certainly not making any claims on their behalf, but this tells me they do "customs", or just don't have all configurations listed. I'd say it's just a matter of changing a couple parameters in their solid model, running it through their CAM software and over to the CNC. It looks to me like they've got the general details worked out. It would definitely be worth the call if I were the OP.

Thanks. Brad.
