My expertise is with the 71-72 cars, so I'm still learning the 3-4 cars. The only differences I have noticed: 340 replaced by 360, the wierd hump in the trunk floor(?), the steering wheels, and I believe the front suspension is different. What other differences?
340 replaced by 360 the wierd hump in the trunk floor the steering wheels I believe the front suspension is different.
Gas tank too, humped to gas tank vapor separator, and that's the reason for the humped floor.
suspension JUST the lower ball joint... pressed instead threated on 74
The seat belts in 74 were different, they had a built in retractor. The bumper guards on 74s were longer than 73s. No cowl vents on the hood of 74s 74s had a seat belt interlock system where you couldnt start the car unless you had the seat belt on. 74s had icons on the gauge cluster.
Retractors on shoulder belt, hidden by rear lower panel. Rear Lower panel. Frame where shoulder retractor goes bolted Underdas wiring harness Undercarpet harness for seats and belt buckles sensors All front belt including female ones. 74 does have sensors one females for a while 73 on retractor. Also 73 male terminals are different. Frame on sides of roof, since shoulder belt is bolted different. Gas tank straps... 74 is hooked on rear and bolted on front rear bumper guard lower braces. Engine harness Seat covers with different vinyl pattern coat hooks Horn relay Advertising buzzers ( lights, key and belts )
Note... some of these even different does NOT mean uninterchageable., well at least you can mount a 73 horn relay on a 74 and backwards, but if backwards, then you won't have ignition key in buzzer
Note2: About interlock, canadian models are different and let you start the engine even with unfasten seatbelts, so control only works like the warning signals control unit

mark: Just throwing this out there for what it's worth. I've come across several sites with VIN information and decoding over the years. www.lynchroad.com, www.maxwedge.com and www.hamtramck-historical.com. Hope they help.
