Yes, the 87 Bird is a fox chassis, but for some reason the Bird/Cougar have different motormounts. I wouldn't have known except my sister-in-law has an 88 Sport w/ the 302. I have gone to several parts stores and after a couple of wrong orders was told they don't make them anymore. Then I tried the junkyard route. I went to every area yard, looked under hoods, dug through piles. The Mark VII is even different. I finally found a set in an older model TBird that someone had scabbed in. But now I need a second set for a second car.
Hey tbirder, have you been to
www.tccoa.com yet? They have everything you ever needed to know about MN12 chassis Birds.
