I had a chance to take a quick look through WW's current manual. The distance from the firewall to the rear bolts on the tray for the motor using the stock oil cooler location and oil filter is 10.5 inches I believe. It can be shortened for remote mounted cooler and filter. A complete explaination and details of the mount and relevant dimensions can be found between pages 92 and 100 of the manual. Any additional supports or tubing is simply cut to fit.
I hope this helps. Steve Glover KR-2 N902G AJO, Ca <kr...@cox.net> I have to add here that there are no specific lengths (that I see) in my manual. I don't know how long to make the pieces. I did email WW and he told me to order 5' of the 3/4 .049 square tubing and 10' of the 3/4 .049 round tubing but that is all he told me. I showed the drawing to my welder and he said he could make them up even without measurements. he will make the tray (easy enough) and then fit it to my firewall. So, it may be an inch or so off from whatever yours turns out to be. I don't like the inexactness of this method but the welder assures me that it is no problem. I ordered my steel from Aircraft Spruce just today. Ray New Orleans
