No, they are different body styles.
No
The hood from your 1994 Cadillac Deville will not fit on to the 1994 Fleetwood. The 1994 Fleetwood hood is larger than the Deville hood.
No, they are different body styles.
no cause a 1994 may have a bigger engine
Yes!
absolutely not
yes
Unfortunately the 2000 Mustang and 1994 Mustang are completely different body styles. The convertible tops are also different, so a top from a 2000 would not fit on a 1994. It might be possible to modify a top from a 2000 to fit on a 1994 but it would be costly and time-consuming; buying a top for a 1994 would be much easier.
no, they are totally different models. the only way it'll fit is if arrangements are done.
yes, 1994 -- 2014 would fit, all are the same pattern !
Really need to know if the hood from a 2003 will fit my 2004
yes
