The opening is about 2" x 6", and is for a 2.5" hose, part number MPOOLSOZN, and was priced at $45 USD each.

The M4 backing plate fit the M2 perfectly, but they were rather pricey.

If I were going to do this again, I would just use this with a 2.5" hose. I would cut a 2.5" hole in the stock backing protection plate and rivet a 2.5" aluminum flange to it. Aircraft Spruce & Specialty Co. has all kinds of flanges for 1" to 3" hoses. 2.5" flange was about $10.00 USD each. Their phone number is 877.477.7823.

Hope this helps.
Good stuff ! Thanks for sharing.

Have any pics of the ducts ?
