So... the engine is in (I’m using the NaroEscape -6 front mount) and, seeming because of the mount, it sits lower than stock. The Patrick Motorsport -6 shift linkage rod I intended on using, wont work. It interferes with the engine case and doesn’t seem to have a workaround. If the engine were 1/4” - 1/2” higher at the firewall, it looks like it would slip in, but alas, the engine is not going anywhere, lol.
I’m tempted to just bend the PMS bar end upward (maybe a couple inches from where it goes from the narrow shank to the bar rod) to give it the clearance but that would change the angle it goes into the rear bushing and connects to the shift lever... so I figured I’d ask if anyone else had an issue with the bar hitting the engine case and any options I might have. I’m OK with modding the old -4 rod too. Might be worth a shot but figured I’d ask here first. The other threads I found look like the stock rod modded is the move. Thanks Rich |

Unfortunately, all of our parts are not produced by highly trained Porsche factory engineers with lots of experience and lots of testing.
Bob's mounts, like the Rich Johnson mount are made by talented enthusiasts with lots of time and limited money. They don't really get the same level of testing factory parts do. So you are likely to have issues like this one. Plus, after almost 50 years, these cars have been customized so much that no two cars are alike. So we build this stuff, and hope everyone understands that it will require tweaking for your use case. I have been friends with Rich Johnson since the middle 90s. He makes great parts, and I have one of his conversion mounts in the 4.0L car. When I converted it from a 2.4 to the 4.0 engine, I had to buy a different mount because the half that fits on the 2.4 won't fit on to a 3.6 engine case. We built a jig on a 901 trans, and made the transmission mounts for the Cayman trans fit the jig. We put the engine and trans in the car, and the trans mounts were almost 2 inches to the rear. I thought the jig was wrong, but when I pulled the engine/trans back out, I found the 3.6 engine mount was about 2 inches thicker than the 2.4 engine mount. This was done to clear the pulleys on the 3.6. It made the engine tin too short on the front too. Because I have a clewett serpentine belt setup on this engine, I shortened the plate in the front mount to the same height as the 2.4 mount. Then everything fit correctly. That is an example of "You may have to tweak it to get it to fit your application right."
