I am looking for a Corvette C3 1968-1972 and seen quite a few converted with headlights as shown on the picture below.
Is it a lot of work to restore headlights back to original?
Thinking if there have been any cutting to the fiberglass?

 

Cost is the largest factor because the headlight assemblies themselves are expensive and if they are old and unrestored they can cost a lot to restore back to smooth working order. The other thing is how much of the headlight location was modified for the scoops. Luckily fiberglass is a very forgiving media and more often than not it's easy to repair. Between the two aspects I would not say it's easy to change back from those after market headlights but it can be done if you don't mine the money or modifications to get it back to stock.

 

To the best of my knowledge, these were all bolt in kits so there shouldn't be any fiberglass work. However, that's no guarantee a particular car hasn't had any mod to the glass. I suggest if you're looking at a particular year, measure the openings and ask someone on the forum to measure there's.

 

Hi s,
I think Mark is right.
If there is NONE of the original headlight assembly parts with the car, you should figure their cost ($$$) when deciding what you're willing to pay for a car.
For example I see them listed for $500 each in one of the vendor's catalogues. Then you might need the relays, hoses, and maybe a switch.
Regard,
Alan

 

I see. Thanks for the help

 

Some of the aftermarket conversion kits bond in; others bolt in. The bolt in variety would be easier to remove.

Regardless of the type of conversion, replacing the stock system is likely to be expensive. You can take a look at any of the on line vendor catalogs and come up with a list of parts and prices.

My advice would be to pass on cars with the conversion kit unless the seller has the original headlights and associated hardware.

 

I suppose you are right it is best to find a car that have the original headlights in place

 

MY advice would to be pass on any car with stock headlights, why? because the replacement parts are getting expensive and flooded with China made JUNK, therefore unreliable, as was my experiences with that operating headlight constant maintenance 16 years ago, somehow methinks it not better today...eh??

SO to go to my site there on shutterfly and see the car with reduced openings, and later Camaro bulbs built onto the Eckler's sugar scoop trays you show in your OP there.....

 

I have always liked the original pop ups on Corvettes

If you think of the vacum system being bad there is electric motors for the lights that is bolt on

I like the the injection you have But it must be original headlights for me

 

If you buy one with the conversion done Ill swap the oem ones that came with my 74 with you. Even swap.
