Shaving 73/74 turn signals. How to.

I have decided to modify a second grille to replace the first one I did, which started out as a very beat up grille with a lot of cracks. I also took some of the things I learned on the first grille and applied them to this one. I took lots of pics and this thread will hopefully help those who have PMed me for more info on the build.

I figured it would be better to start a new thread instead of tacking onto the back of my last thread where it may get lost.

First step is to cut out the old light buckets.

The first two cuts are made with a small, fine toothed hobby saw along the top and bottom of the light bucket.



next, using the hobby saw again, I make a vertical cut flush with the original vertical rib. You will have to finish the cuts from the back.




The next step to remove the bucket is to cut from behind with a Dremel cut off disc. This plastic melts easy with the cut off wheel, so leave yourself some room to clean things up with a file.





Now with the grille flipped right side up again, cut the two horizontal ribs still holding the light bucket to the grille.



This is what you should end up with.



Now with the Dremel again, trim off what remains of the light bucket and square up the corners. You also need to trim down what remains of the ends of the horizontal ribs, leaving the raised pads.



After cleaning up everything with a large, flat mill file, this is how it should look. Note the raised pads that the original horizontal ribs sat on.

Now with a caliper, measure for the new vertical ribs. They should measure 1" x 3.640.





The vertical rib will be square on the bottom, but the top will be at a 94 deg. angle. The 3.640 is the short measurement. The measurement for the rear will be longer. Leave the part a few thousands long and file it to fit. You want a nice friction fit to make assembly easier.




Now you can glue the vertical ribs in place. I used a strong, gap filling super glue. You can experiment with other solvent based glues if you prefer. The ribs should be at an 84 degree angle to the original horizontal ribs.


Now you need to mark the slots where the horizontal ribs will slide in. I use a straight edge held against the original horizontal ribs and mark the location on the new ribs. I dyed the area with a sharpie marker so the marks would show up in the photo's. Now you can transfer the marks tot eh sides of the vertical ribs with a small machinist square.

Here are the basic dimensions for the horizontal ribs. On my first grille, I made these parts 1" thick all the way across, so when they were installed on the grill the didn't match the angle of the existing, top and bottom horizontal grilles. It's hard to tell when it's on the car, but I wanted to correct that problem on this new grille. (The parts I made for the old grille were much easier to make though).




With the horizontal ribs cut and cleaned up, set them in the grooves cut into the vertical ribs and push them flush against the original ribs. (to the right on the picture.) Now with a straight edge held tight against the vertical ribs, scribe you cut lines.






Now just test fit the horizontal ribs and do any trimming necessary for a tight fit and glue it together.



It's late and I'm tired, so if I left anything out, or something doesn't make sense, let me know.

John.

Maybe I missed it somewhere but what type of material did you use for the filler panels?

Sorry about that. I started this thread as a follow up to this one....

https://www.stevesnovasite.com/forums...73%2F74+grille

I figured anyone who wanted to try it already read my first thread.

The white plastic parts are cut from the track used to build glass block walls. It's 4"x4' and should be available at your local Home Depot or Menards.


Here's the finished product with small turn signals hidden behind the grill.

That looks amazing, I had wanted to just go to a 72 front end but I'm going to do this instead and just chop the bumpers to make it look good.

Very nice!
I read your other thread when you posted it a while ago.
What did you use for the glue?

Great Turn Signal Mod

This is a great mod and I really appreciate leaving the 73-74 front end true to the car while cleaning it up. IMHO better than the 72 swap. Great job!

onequicknova,

I must commend you on a job that looks GREAT!!!!


I do have a couple of questions for you...

1. Is this DOT approved in your state?

2. Are you going to relocate the turn signal lenses to another location?

Ovrdrive- read his other thread, I think it's page three, he relocated the turn signals behind the grill. It looks really good and I wouldn't see why it wouldn't be legal if he still has turn signals
