    Re: How to tell if my hood catches / latches are original or repro?

    Richard - I removed my left latch and took this close up of the "diamond". This is the sharpest image I could get. FYI - I also examined the diamond using a 5X jeweler's eye piece - up close and personal - like 2 inches away. You can see a hair on a mosquito's butt with that eye piece. I can assure you that there are no "letter" characters inside the diamond. There is a spear shaped line coming from one corner of the inside of the diamond that points toward the middle of the diamond. It is a clear and sharp cut - looks to be a design feature of the dye stamp. I cannot be 100% certain, I can't "prove" but..... I am very confident that my latches are original to the car, based on info I was provided by the guy that restored it 19 years ago.

      Wow, you guys are going above and beyond to help me learn about these hood latches. I appreciate your time and efforts, especially you Ed as you just removed yours. Thanks again guys. Keep the information flowing and the lessons coming.

        I'd like to amend my post #8. After closer observation, there is a diamond on my driver's side latch...tiny but it's certainly there.

            It's upside down.

              Gary thanks a lot for that photo. More confirmation.

              Leif, thanks for confirming and amending your previous findings.

              Ed, Good eye re Gary's photo, but I'd venture to guess the orientation of the diamond shaped manufacturer mark could be in any position..

              Also thanks for your photo. Nice to do that for this research. I'll play around with it.

              What's also interesting is your "rivet" holding the stamped bar. Yours is "19", all others so far are "91". Oh boy, more fun.

              Later I'll get on the laptop and do some more comparisons. What's really interesting is Brian's diamond stamp with those letters. The mag'd image shows it so clearly. Unless it's some kind of weird reflective optical issusion.

                Rich,

                First, re Gary's pic being upside down..... I was just bustin' his chops on that one - but I think you (and I) are correct.

                91 vs 19..... that I did not notice but you are correct (again). How did they do that? My wild guess is that my hood latch was manufactured on a Monday morning.

                On a related note...... MFRG logo's..... that diamond on the hood latch is there for some reason.

                It triggered something in my mind. I dug out a pic of my rear suspension cross member, it has a small dual diamond MFRG logo stamped into it. The word DANA is in one diamond, the word Detroit is in the second diamond. Obviously diamond shapes were popular MFRG logos back in the day. See the attached pic. I also have a part # stamp on my cross member, 3817927.

                  Isn't Ed's photo in post #12 just a reverse image of a number 91?

                    Leif if you zoom in on it look closely at the upper "tail" of the 1. It's pointing left just like it should (1). The "9" is a bit odd but blurry, but stamped characters can sometimes look like they're raised, showing shadows.

                      Rich,
                      This is a horrible close-up of Ed's picture...reversed (and, my tracing abilities are negligible). What do you think? And, we all need to get a life...spending this much time on a rivet

                        I agree with you on both points, the quality of the pic and us chasing the meaning of the life of a rivet. But, you gotta admit..... we did it in grand NCRS fashion!

                          Just like getting a PhD. Learning more and more about less and less.

                            HaHa, I've been busy for over 2 weeks straight since my return, outside cleaning up from hurricane Ian's winds, fixing broken stuff in and outside the house, pool shocking and cleaning due to a failed chlorination system, getting stiffed for a new one I just installed, rebuild the pump, repairing Intermatic timer and pos Intermatic offshore switches, deteriorating offshore plastic parts that only last a few years now(blinds, etc), disposal leak/replace, broken lawnmower and utility tractor, dead batteries, damaged gutters, and more.... Seems I fix one thing and 2 other things break since I got back. Did I mention down here the daytime temps in the mid to upper 80s, with a feels like mid 90s? I'm losing weight.

                            So when I can, I get on here for a nice rest and relaxing break and just love using the brain instead of my old sore body parts.

                            Gimme more rivets to research. I'm ready.

                              Circling back to the purpose/intent of the thread and given the information in post # 15, have we come any closer to being able to differentiate between an original vs a repro?

                                You may have to actually purchase a reproduction and see how it compares.
