Okay, a super nice gentleman located one for my beloved T-28D "Airforce" Trojan!
My Trojan's Firewall finally got to a point of no return so, needed a newer one!
Received the Stock Plastic Firewall on Thursday, September 15th, 2016 and in perfect conditions.
I wasted no time and cleaned off / took off the rubbery glue and it looks ready for installation!
Thanks again!
