I read that Van's offers a cross member that bridges the gap in the baffling recess for the oil cooler. Anyone know the part number? I can't find any reference to it in the parts catalog.
I recently replaced the air seal fabric on my 18+ year old RV-6. I did not have CB-705B but from the drawing shown, was able to fabricate one without too much difficulty. Now if you need to order aluminum to make one, you would be better off just buying the part from Van's.
