At Medford I ripped the sport mount right out of it's housing on my last autox run.

Lucky for me Mark spied it, borrow one (Thanks again to a Great 914 owner) and installed it so we could run the enduro.

Anyway, decided to put in the stock rear mounts today.

What I discovered is that someone had changed the engine bar, shaving off an inch of the end mount, that the M10 bolt goes through, so that a sport mount could be used.

So if you used the solid mount there was an inch gap between the U channel (solid mount) and the mount bar.

I know, you could use washers and or machine a spacer, but neither of those were on the agenda for today. Although I did get close when my local hardware had, believe it or not, a metric M10 1.5 threaded spacer that was an inch long. My M10 bolts were not threaded all the way so this wouldn't work and I didn't want to wait to buy new bolts from McMaster Carr.

So decided to re-install new sport mounts, which I had just bought, but what bothered me was the steel sleeve through the rubber donut was bigger than my M10 bolt. This slop undoubtably didn't help shifting.

So back to the hardware store to check for something that could work as a sleeve. Well I asked the guy behind the counter and he said he'd just got in some metal sleeves and showed them to me.

One fit the M10 bolt tight and looked to be about the right length and thickness to fit inside the metal sleeve on the sport mount.

So bought two sleeves and went home. Sometimes you just get lucky - they fit just about perfectly and were even the right length.

So I just JB welded them into the sport mounts and bolted everything back up, this time using the right concave washers on the top and bottom. (Thanks again Mark).

I think part of the problem with my old mounting, other than not having the washers, which was a BIG problem in itself, was that the M 10 bolt had about an 1/8 of an inch slop going through the sport mount.

In any event I think the car is going to shift better now.

Man, sometimes you just get lucky.
