just wondering if anyone can tell me if my flowtech(shorty) headers will fit on my 84 5.0. The box they came in said for 86-93 5.0. Is there a difference? The model number on the headers is 12107FLT. If it makes a difference shes a 5 speed

 

They should bolt right on the 5.0 is the same(other than no HO) as long as it doesnt have gt40p heads

 

thanks, now I just have to get the flowmasters to go with my bbk o\r h-pipe.
