Technical Halibrand adapter

Picked up an adapter that says Halibrand 115 fr on it not shure what it fits on or too. Or if it's Halibrand for sure other than what the sharpie says. No casting number or markings. Any help appreciated

 

My guess would be to adapt Ford housings to a Champ QC. If so you would need two, unless someone only needed one.

 

Nobody made a Champ style quickchange with only 8 mounting studs.

Might help if we knew what size it was.

 

I think it is an adapter to be used with an open tube, sprint car, axle to use a champ R&P on a tube originally meant for a V8 R&P when converting from V8 center section to a champ center section.

Halibrand part H - 856

 

I will get some measurements on it. And post them.

 

Not for a Champ with only 8 holes. The 10 holes in the middle is for the early Ford trumpets.

 

This is a Champ to V8 adapter

 

It is 8 1/4 in diameter

 

Any more possible info appreciated thanks to those who have already
