    Hi Dale,

    Could you post a picture of what it looks like. I'm sure the answers will be more accurate.

    Thanks,

        Hi Dale,

        Thanks for the picture. Unless I'm missing something, I don't see a problem. If this is the original, it looks just like my repo for the L-36, of course, upside down. Others may have a finer eye but I would not add extra holes. Am I missing something here?

          Many sleeps ago I bought a new bonding strip (as you call it) to replace a broken one. It came with correct rivets which I was able to install so the change was undetectable. I believe I bought it from one of the large vendors in Michigan -- but I can't recall which.

          BTW: That reproduction box has show chrome and will usually result in a 10% deduct for Finish. The original finish was "flash chrome" and the box was not polished. It was plated just as it came from the forming die -- stretch marks and all.

            Terry,
            There are two sets of holes there, and his original tab went in the other two. As best I remember my 1970 had three holes and the tab went in either the bottom two or the top two -- depending on the carburetion.

              Dale, is this '68 tri-power box different in any way from a tri-power '69?

                Here is a picture of my original '69 L36 box for your information. If you are wondering about those nuts on top, I'm just trying to get the lid farther away from the coil wire. Absolutely hate this shielding business...what a pain. I never listen to the lousy radio anyway.....

                  Just got home and I looked up the PN of 68 an 69 in the AIM and they are the same on page U69, A6. I guess if I can find the rivets I'll move it up and flip it to the top holes as it is a totally correct box. Terry, did you see the difference in the round carb strip and the three duces?
                  Thanks to all.

                    I don't know if you meant me or Buchanan -- but I do know there are at least two style ends on the tab -- based on my research when I was involved in the replacement I spoke of earlier. I no longer recall which shape goes with which carburetor, but I think that information is in the AIM.

                    Edit add: There are also several styles of box -- the part number not withstanding. One style has two separate pieces for the sides, and on the passenger side is held together with two silver Philips head screws. The other has the two pieces for the sides permanently attached together on the passenger side with spot welds as in Dennis' post number 8. Also the 1968, and some 1969 boxes came with an opening for the coil primary wires in the rear of the box. Later boxes did not have this opening.

                    If you know what style your box was originally, I recommend finding an exact replacement. If the original configuration is unknown -- the one with two piece sides is far superior in terms of ease of maintenance of spark plug wires and access to the parts inside the box.

                      I blew that. Yes, the 68 and 69 are different just as Terry said. I was looking at the part number for the box top not the box itself.

                        Terry Mac is right, it is depicted in the AIM

                          Over the years i have found it is better to remember where the information can be found than to remember what the information is. It is also easier -- less to remember.
