[74C10Y]

Wow!!! Hard to tell from just those two pic's, however you got some work cut out for you to put it back to 74. Alot is going to depend on how professionally this update was done? is it a weekend hack job? or was it done by a shop? Also do you have a complete 74 grill/bezel's/trim/with all the correct hardware? It can be done, but it depends how much time/labor and money you want to put in to it? Grill and hardware is different, headlight bezel's and chrome trim is different, 74's had amber park/signal lenses.

Best thing is to remove all the front face, see if there is prior front damage/rust/alterations to supports and brackets. You can obtain original parts or repops, but be careful mixing the two for fitment. Also I don't believe you will increase the value that much, if it's more preference and originality.

I would seek out someone who has already tackled this job for advice, as well as seek out using original parts vs reproduction and costs? hope that helps. Good luck!
