Distributor (With Vacuum Advance) All Aircooled Models 1961 to 1979

I bought this unit to replace my earlier stock vacuum only dizzy, the unit with the flatter style cap and 2 piece points.
It does appear that this unit is also vacuum only which is great for stock engines with the PICT -1 or -2 carbs like mine.
Its generally very well made and great for the price but it isn't a BOSCH/OEM manufacturer. For instance there is a small ball bearing on the moving plate that ensures the plate only moves 'around' and not up and down but fit and finish is a little rough so the parts fit is rather tight and edges are sharp.

My only real criticism is with regard to the overall orientation of the distributor body.
When reading the manuals on how to replace a distributor you have to make sure that on the 'old' dizzy you rotate the engine to TDC and that the rotor is pointing to Cylinder 1. On OEM dizzys with the rotor cap off the rotor should then roughly line up with a line scribed on the side of the dizzy.
You then remove the old dizzy and if you look into the hole you can see the dizzy drive should be parallel with the bottom pulley. You then reverse the procedure and drop the new dizzy into the hole making sure that the drive engages correctly.
However on this replacement unit the when installed correctly the rotor was/is pointing towards the generator stand ie roughly 90 degrees too far anti clockwise.
That means that the body of the dizzy is now cocked and the vacuum can actually points 'into' the engine rather than towards the engine lid. And as somebody else mentioned there isnt a scribe mark on the body to confirm that you have lined up where Cylinder 1 should be.

I am assuming of course that this is how they all are but perhaps Ive got a rogue unit? Can JK confirm this on other distributors??

Recently fitted and so far so good. Always used 009s in the past but the thinking on the web seems to be to stick to these.
