Need some Critique on my 69

[bkhpah]

The Delco Morane stamping on the power boosters I have seen are all over the board. From very faint stampings to none at all. I have also seen the DM logo in the 2 o'clock position on unmolested low mile cars. While, not typical, they are made that way. Just like the differences in font size in the date and application code. Just to many variables during the model year to say it could only be one way. Also the pinch clamps on the PCV valve should have squared off ends. The kind that rip your finger's open square. Later style pinch clamps used a rounded end. Much more finger friendly..BKH
