I have a new header that I have no idea what it fits.

Mac's web site was no help.

It is the same diameter as .40 tuned pipe.

It is a bolt on style with a bolt spacing of 1.1875"

Any ideas?

Thanks, Tony

Anybody?

Help a brother out!!

I have been in this hobby for 40+ years and can"t figure out what this fits.

I have glow engines from most mfgs. and nothing fits.

Put your minds together and help me out!!!

Thanks again, Tony

Picture?

A little quick research and that bolt spacing puts it down in the .10-.15 engine size range or a very small port .20-.25... Which brand will be hard to determine. If it would fit my OS .15 CV-A ( 27.5mm (1.085") bolt spacing) I would love to have one.
