Size Matters

[billybaloneey]

A new owner here, so forgive these seemingly simple questions.

I know that the rear end body parts on the ZR-1 are bigger than the standard C4...to accommodate the wider tires.

1) are the doors a different size?
2) are the rear side light housings a different size?
3) are the brake and turn signal lenses a different size?
4) are the backup lenses and license plate assembly a different size?
5) is the rear end carpet and internal trim a different size?
6) is the "CORVETTE" script a different size?
7) within the ZR-1 line, 90-95, were there any parts that changed size/fitments from year to year? In other words will the early ZR-1 body parts fit the late model ZR-1's

Is there a list published anywhere that points out all of the differences between a ZR-1 and a standard C4...front to back? Obviously 75% or more of what's in the engine compartment is unique to the ZR-1. Other than the engine itself, what are some of the other items in the engine compartment that are ZR-1 specific?

Thanks,
Clint aka billybaloneey

You forgot to mention the "grin" is wider (on the ZR-1 drivers ).

I did not think the Brake and Turn Signal Lenses were a different size (#3)

I never measured them to compare, but couldn't help but notice the proportion appeared to remain the same, in spite of the wider tail. So, I wondered if the ZR-1 lenses were not a tad bigger. Someday, I'll have a ruler along and satisfy/confirm what I suspected for some time.

Guess I will look up the PN for any given year 91-95 and compare to the narrow body, but I am betting they are the same

Reverse light ARE different though

For #6 and #7, the "CORVETTE" emblem is larger on the '91+ models (of which non-Z's didn't have an emblem anymore). The 1990 has the same sized emblem as all '84-90 'vettes.

Yes, the door line is different in about the middle. You can see it starting to bow out.

2) are the rear side light housings a different size?

No, they are the same.

3) are the brake and turn signal lenses a different size?

No, they are the same.

4) are the backup lenses and license plate assembly a different size?

License plate frame (black portion) is different. The back up lights are the same.

5) is the rear end carpet and internal trim a different size?

No, the inner tub is the same. So the carpet is the same.

6) is the "CORVETTE" script a different size?

90 is smaller than the 91-95 CORVETTE emblem. But in 90 they were the same size.

7) within the ZR-1 line, 90-95, were there any parts that changed size/fitments from year to year? In other words will the early ZR-1 body parts fit the late model ZR-1's

Yes, everything will bolt right up, or I should say bond right up in certain cases.
