Is the engine tin underneath the engine the same for all years?
I am missing mine for my 75 1.8. Thanks for the replies!

No. There are two pieces that are different on your75. The ones under the cylinders. the one that goes under the passenger side is hard to find.

There are the tins fastened to the bottom of the cylinder heads. Those are the same for all years.

There is one more piece further down on each side, which attaches to the case right near the bottom, and to the heat exchanger. Those vary; there's one version for the tail-shift cars, one for the 73-74 side-shift cars, and one for the 75+ cars.

l&r warm air guides...what you need depends on what heat exchangers you currently have on the car. for year correct heat exchangers, the 75/76 versions fit only 75/76 hes. earlier pass side is the same all years. earlier dr side is dependent on whether you have a tail or side shift trans.
