as far what interchanges and does not and also what are 4th gens notorious for having problems with

 

[77Concours]

Well, there are many. I'll try to list what I know but you might want to PM Philip (that's his username).

Anyways

1. The dashboards from 75-76 are slanted, 77-79 are more of a boxy rectangle shape

2. If your car has A/C I do believe the A/C set up is different than that of a 77-79

3. Usually all interior parts interchange. Except the dash that I mentioned above.

4. ALL exterior parts interchange depending if you have a 2 door, 4 door, or hatchback. Grills from 1975 required certain brackets which are also the same as a SS/Rally grill which was also offered in 1975. Grills from 76-79 could vary (Concours, Custom, or SS/Rally). I had a Concours which we did a front end swap with and the bumper filler was different. Tail lights also interchange for the exception of the Concours lights that had 3 bars instead of 2.

I hope I put that in the least complicated way possible if you need pictures let me know.

thanx man i lookin at buyin a 79 for a daily all original driver but some time down the road it will become my parts car for my 75 how different is the a/c will it kinda fit or not a chance?

The entire AC set ups are interchangable the specific parts changed over the years. 75 -76 have an expansion valve type system and in 77 they went with an early CCOT system. I have a 76 I can snap some photos of and post along with the 77 set up in my car. The later set ups are easier to convert to 134A IMO.

The position of the rear brake hose changed around 77, from being over the center of the axle to attaching to the drivers side axle tube. At first I thought it was an 8.5" vs a 7.5" difference, but later it appeared to have been for both rear ends.

[Philip]

If your 75 did not leave the factory with AC than the factory set up can not easily be added. The firewall is cut different.

1979's have recangular headlights with unique fender extensions, headlight bezels, grille and front bumper filler. Other than that and the other differences listed above (dash, A/C, misc trim) they are basically the same from 1975-79.
