    Phosphate finishes

    I'm almost ready to assemble the refurbished front end assembly components on my 68 and was curious on just what bolts on the front end had the black phosphate finishes,

    Such as,

    Two spindle main bolts/nuts holding components together?
    Tie rod tube clamp bolts/washers/nuts?
    Steering damper plate to relay rod bolts/nuts?
    Steering damper bracket to frame nuts?
    Sway bar bushing mount bolts?
    Control arm bushing bolts/washers?
    Lower shock bolts?
    Frame end extension mounting bolts/washers/nuts?
    Steering box to frame bolts/washers/nuts?

    Whew! thats enough for now.

    Is there a book out there that can help me identify bolt/nut finishes.

    Thanks,

    Chuck

    Chuck,

    Try "1953-1972 Corvette Chassis Restoration Guide" by Joe Tripoli. Available from the NCRS store. Click on the button at the top of the page.

        Re: Phosphate finishes

        Chuck, following info is what I observed on MY car, and MY car is a 70...a late 70. Accuracy of my observations, particularly BLO versus BLP, could also be open to argument:

        Two spindle main bolts/nuts holding components together? Can't find info.

        I remember the big fat one above being zinc, but the two lower ones...?
        Tie rod tube clamp bolts/washers/nuts? BLO/no washers/zinc lock nuts
        Steering damper plate to relay rod bolts/nuts? ?(No dampers after mid-60s?)
        Steering damper bracket to frame nuts? (PS cyl brkt) BLP nuts
        Sway bar bushing mount bolts? BLP
        Control arm bushing bolts/washers? BLO/DGP (bushing retainers)
        Lower shock bolts? BLP
        Frame end extension mounting bolts/washers/nuts? BLP/BLP/BLP
        Steering box to frame bolts/washers/nuts? BLO/BLO/natural

        The short answer to your question about a book...No. Tripoli is an excellent general reference and I would also recommend it, but it will be woefully inadequate for putting a car back together with all the correct finishes and headstamps.

        To specify all the finishes on every fastener, for every model year would be a mammoth undertaking in itself; at best, Tripoli hits some high points. If you then add in the fact that phosphate finishes may vary from black to gray, and headstamps can vary over two/three or more styles during the model year, you begin to doubt that a comprehensive catalog of "correct" fastener finishes/headstamps will EVER exist.

        The best reference is the car itself: if it was too rusty to determine the finsihes/headstamps accurately, then reference an original car as close in model year/VIN number as possible.

          Re: Thanks Chuck

          My non power car DOES have the steering damper setup.

          A fluke?

          Hmm.........maybe it's that rare one of a kind feature only on my car and nobody elses!!

          Should be worth about 50,000.00 don't you think?

          Thanks for your help Chuck, this will get me going in the right direction.

            Re: Thanks Chuck

            Chuck, I don't have deep knowledge on 68s, but I have a great respect for Joe Lucia's knowledge and references. I thought Joe posted in a recent thread that the dampers weren't installed after some late mid-year, but that the relay rod continued to have the damper hole (unused) for a few years afterward.

            If I understood Joe correctly, then I would suspect someone had retrofitted the damper. But, unless you are having the car judged, it's really immaterial...but, I believe I would have "retrofitted" power steering...something to help turn those big fat tires, rather than just keep them from shaking.

              P. S. What Joe Really Said...

              Chuck, I rechecked the archives, and it appears that the steering damper could have been used through early 68 on low horsepower small blocks, but was not used from 63-68 on high performance small blocks and big blocks.

              Joe indicates that absolutely no provision was made for steering dampers after 68. Paul Borowski also posted that he has a relatively low mileage early 68 with an original appearing damper installation. You go, girl!

                Chuck and Chuck, my original owner 68 with the high performance small block L79 has the steering dampner. In fact, the original fcatory installed steering dampner is still on the car and available for inspection.

                  The only 63-67 small blocks that were denied the damper were those with power steering and 63-65 with SHP mechanical lifters and "6 quart" oil pans. For early 68's, I would expect that damper installations would have included base engine and L-79, equally.

                    Re: That's my deal

                    Like I said earlier, my June production 327/300 non-power ride does indeed have the damper.

                    It's interesting though that my A.I.M. sheet even though depicts the damper, lists it as DELETED.

                    Ok Chuck maybe I'll settle for $35,000.00

                    Thanks for the feedback group.

                      Joe my 68 is not a early or late, it is a mid Feb built 68 which puts it about right in the middle of the 68 model year.

                        Re: Mine's Original Too

                        From the sounds of things, it really didn't matter if the damper was on or not performance wise.

                        Kind of like a flabbercaster switch on a podnorator valve I think.

                        Well it's going back on regardless.

                        Thanks for the help folks,
