I am flying evry day with my 5 Vixen with smoth cool. I have a 912 UL 80 HP and I have recently bought a 912 ULS 100 HP. I want to use it asap but I need to built a wooden firewall to instal and prepare for the swap without loosing time during the swap. I have ordered a new heavy duty mount, arms and rubbers for my new engine (with some other parts for around 1400 us$ + 500 shipping to France) from John at Kitfox, but he told me that he have no numbers to built one and that I will need to get the dimensions and make the mock-up from my aircraft..(maybe he prefer to sell me one new one.)
So my question is : does some one can tell me numbers for that or just PM me a drawing of the firewall by following the contour of a new piece on some paper.
Thanks for your help.
