Yikes! missing engine bolt

There is one "weird" bolt on a VW, but I can't remember if it is the driver's side or the passenger side top bolt.  You'll know, because it has a flat on one side to allow clearance to get it in.  If you don't have a bolt with a half-moon head, it's probably missing.  (Although I'm having thoughts that the weird bolt is on the Starter side......)

Not to worry, though, IIRC it's just a semi-normal 10mm X 1.5 pitch but I can't remember the length (Plus, I've been working on an '83 VW Watercooled for the past month to confuse me).  Usually you can get one at a local hardware store and then grind off the head to fit - the half moon will keep it captive while you tighten it.  Metric or SAE - it doesn't matter as long as the bolt shaft fits the hole and is the right length to get a flat washer and a lock washer on the nut end.  I have a few kicking around here.....want me to through them in the bin with everything else?

Thanks Gordon. The flat sided bolt is the top bolt on the starter the one that's  missing is on the driver's side. It might go to a welded nut but the engine is coming out anyway so it will be easy to figger out then. I'll bet I can get one at Ace.

I was just a little freaked that I drove it for 20,000 miles without ever noticing it.

Isn't the starter on the passenger (right) side? And as Gordon said, they're 10mm bolts (and studs on the bottom). And the nuts are 17 or 19mm. On the left side, the case has an insert for the bolt to screw into because the doghouse cooler is in the way of a nut being tightened by a wrench. Al

Roger that, Al.  Should not be a big deal, thanks.

I'm sure I'll come up with a few more stupid questions as I get farther into this project. I still have several more things to address before I'm back on the road. It kills me to take it off when the weather is still so nice here but some stuff has to get fixed before Spring.

No questions are stupid, Al. It just means you're "less experienced". I will share what knowledge I have anytime.

Thank you, Yodda. The force strong within you it is.

True that is.
