Several of us in the past have posted pictures of dipsticks from survivor cars or cars that have been owned for a long time and there has been some debate or doubt on what is considered correct in a 68 Z/28. In 2015 Danny had his 05E Butternut Yellow Z/28 at MCACN and he asked me if he could borrow a gray tipped round handled dipstick. I brought a spare I had but the main point was he had been told his was a replacement and it should be a round type. While at MCACN there was a 68 04D survivor car in barn finds. It had the exact same dipstick, thin handled gray tip with an “E” stamp. Recently with the help of several individuals I’ve put a small population together to assist with some analysis, but first a review again of the flat type handle gray tip dipstick.
Pictured displayed before of the 04D & 05E 68 Z/28 dipsticks at MCACN 2015.
Note these flat handle gray tipped sticks both have a “E” stamp which several people including Pacecarjeff have stated that is what is normally seen with these flat handled sticks. The round handled gray tip dipstick is normally stamped with “M.”
Now Jerry’s 07C Z/28 stick which is the same as the 04D & 05E shown.
And the handle of a 07D Z/28 with the same handle as the 07C, 05E, and 04D.
Another needed review involved the location and similarities between the two sticks, the gray tipped round handle vs. the flat handled gray tipped stick. Here is our round handle!
Now putting our round handle gray tipped stick beside the 07D flat handled gray tipped stick the location of the ADD and FULL marks are in the same location as the round handle stick. Note the difference in “E” stamp and “M” stamp.
Granted this is a small population but interesting and I’m confident there were two sticks used. Here is a chart of what we have so far but looking to add more 67 & 68 examples. Paul, can you confirm what stamp is on your 02C LOS Z/28 stick?
1967 Z/28 Dipsticks
06A LOS 67 Z/28 Brown Tipped round handle 6000 mile Z/28 “M” stamped
07B LOS 67 Z/28 Gray Tipped round handle “M” stamped
Start 1968 Z/28 Dipsticks:
01B NOR M stamp
All of the above have the round handle with gray tip.
04D 68 Was at MCACN 2015 in barn finds
05E 68 Danny’s E stamp
06A 68 Dave’s E stamp
07C 68 Jerry’s E stamp
07D 68 Skip’s E stamp
All five of these NOR Z/28’s have the same flat handle gray tip “E” stamped stick and all of them are survivors. Chances of all 5 of these having service replacement sticks is extremely unlikely IMHO. Plus there is no part # on stick similar to other service replacements or pierced area like later service replacements.
