    C5AF on the early 66 cars. I don't remember for sure where the exact cut off is but I remember researching my Nov 65 built-66 model as being the C5AF stamping. I do have the C5AF and C6AF (both 42 amp) stamps as well as the correct font date stamper.

    McFly, I took a look at those and had to put the "brakes on" to do a little more research.Thanks for the tip though.


    I think what I may have is a 67 half of caliper mated to a 65/66 caliper half. My calipers have a 3/8 port and that would be the 65/66 half I believe with a engraved cast number number of A 71312 on the side. The other half of my calipers have the cast in L shaped boss that protects the crossover tube from getting pushed into the rotor. I read somewhere that was an indication of a 67 caliper. I see a raised casting number of 71315 on the top corner. Can anyone with a for sure pair of 65/66 calipers tell me what number I should be looking for. Perhaps a good set of pics showing both top and bottom.


    Thanks Ray

    Bob,


    Thanks for the quick add to the thread. Underhood temps will play with colors too as in the purple/blue thing. Radiator paint will have the gloss die off to something flatter after heat cycling as well.


    I was researching a theory that the date stamp would be either white, yellow, or orange dependent on the shift but you kind of shot that down-which is good. You have seen tons more than I have.


    My theory was based on the heater motor that I mentioned. Mine followed the Oct 22 1965 date format and was stamped in white. I thought I had seen one stamped in yellow but I can not put my hands on that unit.


    Just in closing my heater box is stamped in yellow Y5LC. The letters are neat and uniform about 1/2 inch tall and really are lacking a font or style. Then to my amazement upon close inspection clearly they have brush strokes in the paint markings. They just look too neat and uniform to be done by hand. Don't want to stray to far from the thread but any comments on this finding.

    Bob,


    Any pics of the date code so we can see style and placement? Was the format like say the date code on a heater motor= Oct 22 1965 made with a common pump style date stamper consisting of rolling the wheels for 365 day capability?


    Also I hear your guy say the alt was fixtured, then stamped. Does that mean the stamping action was actually done by hand-allowing for perhaps a bit of a crooked stamp? I was always curious if the ink stamping was done by a machine and therefore more consistently straight in it's placement.

    There is allot more information available at VMF on the subject. Lorne Willard has lots of info to digest but most of the pics have expired.


    My jack does not have the stylized A on the top but is otherwise identical to the jack shown in this thread. One thing we know for sure is the jack shown here is a April 66 Metuchen and I am certainly not disputing that good piece of info.


    Reading and following MCA judge Willard's research he suggests that the 65/66 jacks had the threaded bar "nut" rather than the U shaped bracket and has 2 washers ahead of the 13/16 jacking nut and X rivets all around.


    I wonder if the Apr 66 jack is considered a later mid year design. A design that was carried through 67,68. Since my jack does not have the stylized A and 1/4 inch hole in same vicinity,for now,I am going to say mine is a 67 or 68.


    It appears date coding was seen on 69 and later jacks.


    Lastly the jacks that look like course thread are in fact just that. In other words when you see a fine thread jack you will know it. I don't have a thread count per inch but they are about double that of the course thread style. Course thread measures about 6 threads per inch.


    What we need is more pics of known 1 or 2 owner original jacks.


    Perhaps someone knows Lorne Willard and could ask him to post his most recent research or cut and paste his lengthy post over to this forum.---Ray

    Just to add to this old thread and bring it back to the top. I too am looking for a Nov 65 SJ jack and starting my research. Wish there was more info available.


    Anyway just wanted to say I had a jack given to me that is identical to the Apr 66 Metuchen jack pictured with u shaped bracket and for what it is worth the sticker on my jack was on the flip side, same position. Would like to see a pic of an early 66 SJ jack from a known original car.


    Also anyone have a comparison pic showing a fine thread vs course thread jack? Maybe someone can count the threads per inch on a known fine thread jack and post that info. Someone earlier said both fine thread and course thread jack came with the u shaped bracket.

    Revisiting this alt stamp issue I see on page 43 of Tony Gregory's book, 4th edition there are 2 pics of the correct hipo alt but placement of the stamp varies. In fact upon close inspection and when holding a correct case in my hand it looks like the stampings are 180 degrees different OR the alt was stamped both top and bottom. My guess is the 2 pics are actually different views of the same alt.


    So what's the concensus on Autolite stamp placement?
