    Gas tank 1972 Shim marks

    I took the original gas tank out and replaced it with a new Anderson.When I got it on the ground the tank was good but the hose on the side was cracked.Than I put the new one in with new hoses.Now that I know this should I put the original back in.Is there a big hit for the new one? Only glue left on tank sheet Sorry But up under the tank on the body has at least 6 pencle markings.So maybe I answered my ? lets go get a look at the markings.
    Shim marks/ Where on the back end are the shim marks?Are they hard to see.If I can see faint markings can I rechalk them?or take a photo of discolored metal.Denny72

    Re: Gas tank 1972 Shim marks

    Shim markings will be immediately adjacent to each body mount location, and will be marked on the outside of the frame rail.

    If by "Where on the back end are the shim marks?", you mean the shim marks for the #4 body mount, mine were marked on the side of the frame IN FRONT of each #4 mount. There is about 2"-3" of frame rail between the #4 mount and the rear cross member...that's where mine were marked.

    If you can see the markings, I would take the picture without tracing over them...a good quality camera should be able to record what you can see. I would trace over faint characters only as a last resort, and then only to document them before a restoration process that would obliterate them forever. Once they're traced over, they're not original anymore...no matter how careful you are, they will be slightly different from the original writing.

    So, I guess all the work means you have decided not to go for Bowtie?

      Thank you 20817
      The last time it was looked at they had a hard time seeing the marks,And I was not shure where they were at or what to do.So ask a PRO 20817 photo only.
      Bowtie... I will to put the original gas tank back on.The only work that I have done was take off all the non GM and put GM back on,That list is small. I will say tracking down NOS is tuff but very rewarding.Rember this car has been looked at 2 times,so most of the bugs are out.

      The next is the BEST of all. NCRS. In front of you boys

      I will say I have been a big PITA and now it is show time for the car. Chustnut Mtn
      Thank you for the info 20817 Denny72

          Bowtie means don't touch a thing. Gently clean, replace nothing.

          The EXACT part originally installed on the car, regardless of its current condition, is the part that the judges want to see. Replacement parts, no matter what their heritage or lineage, receive no credit.

          I was surprised in your recent post when you said you had replaced your gas tank. Was it leaking?

          I saw your car at Bloomington. It's a very nice car. My advice, and this is only mine, is to leave it alone, replace items only as they break or wear out, and drive it out in the country (away from traffic) on nice days or to judging events. It's a nice car. Now enjoy it while taking care of for the next owner.

          Have fun.

          Patrick

            Strictly hearsay from a discussion years ago (the late Dale Pearman was a participant)...Bowtie judges are looking to see if fasteners had been disturbed; it they've been wrenched, those particular fasteners no longer qualify as "Bowtie" because they've been disturbed from their original installed position; it may indicate parts have been changed, etc, etc.

            We told you before...If you are pursuing Bowtie, don't be doing any wrenching on the car unless absolutely necessary to make it driveable. Just gently clean it, and, uh,...some said to wipe used diesel motor oil on the rusty areas sparingly...Remember?

                    There were a number of folks preaching that wrench marks on a fastener meant automatic Bowtie exclusion. THAT HAS CHANGED, and was not universally true even back in the day.
                    Wrench marks, however, do invite increased scrutiny -- better for all that there are no wrench marks.

                        The wrench marks were from non GM parts and old owners cant help that.
                        I got to go guys the other day the posts were about reset cables.I was going out to the garage to check mine and my wife said to me I cant win.I may have said something about turning back some of her miles.So I have to post and run. Denny72

                          LOL!!!

                          I stopped by at least 3 times but never saw anyone who looked like they "belonged" to your car.

                          I spent WAY too much time drooling over that yellow LT-1 car near yours. I think (?) that based on judging results it belongs to a Mecum. I would have given him cash on the spot for that car and cancelled my 2008 order. That was a NICE car that would have been a great twin to my own 72.

                              As I recall, the silver one in my picture had your name on it in the window. So, my "assumption" was that it was your car. Also note the Survivor sticker on the passenger's side which is not present in the car towards the rear (as far as I can tell or recall).

                              Is yours the 72 towards the front of the picture with whitewalls and the NCRS plate, or 71 in the rear of the picture with white letter tires and no NCRS plate? The one in front appears to me Pewter Silver like yours and not Steel Cities Gray.
