Hi,
I have had to redesign the regal Eagle several times because of fan and engine changes.
The last one is for the dynamax.
There is no bottom belly pan, fan sits on the bottom sheeting, leave about 1/16" for the thickness of the molded inlet. If you bought a kit for a Byron fan you will not have the inlet ducting ( sorry ) it is available and I would send it at cost + postage, If you need more help e-mail [email protected]
