My 87 Cutlass was stolen and stripped...Ive had trouble finding a header panel setup that was in as good condition...Not that I am wanting too but am I able to use the header panel of a Regal or Monte Carlo???

 

Did you have composite headlights ? If so there is some big differences Even calls for a different core support Call your local salvage yard they can look it up in a Hollanders

 

There is a different core support between the different models, why don't you use one from a cutlass. Ebay has had a few that I've seen, gbody.com has had a few, they are getting harder to find but you can still find them with some digging.

 

Monte and Regal header panels are different and won't line up with the fender lines. Cutlass header panels are on ebay all the time. I've seen several in the last few days.
