I have a '72 car here & a '70 dipstick/tube. I'm curious. I'd probably sell the '72 one I have. Same on 4BBL throttle cables. '68-71 & 72. Not sure the difference there either.
Going through the same problem right now assembling my 72 350 engine. Wouldn't be an issue but, I have numerous parts from other engines mixed within. My dipstick rod has a part number on the bottom that indicates 72, according to parts manual. It does not have rubber handle but plastic tit on the end. Green I think. (similar to top photo). Can check tonight when i get home. As far as the upper tube goes, I am at a loss what is correct. I have a straight one and a curved one. Chris.
