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 |

You can't use a stock 4 side shift bar as is in any way, shape form, or fashion; it's got to be modified. When I was making shift bars I would use an early tail shifter and use those bends. I quit doing them when 3 other guys started making them too. No animas, just not worth it for me.
Basically the bar needs to go about 1/2" down and away from the centerline (looking from the back of the car at the firewall) at about 8 o'clock, then back up the same way at the back. Also the rear that goes into the side shift console isn't straight, it's got a bit of an angle to it. All you've got to do is take off the coupler clamp it in a vise and you'll see the angle at the tail end that you've got to maintain |

All you've got to do is take off the coupler clamp it in a vise and you'll see the angle at the tail end that you've got to maintain Noted. Yea, the rear section into the side shift guide being "not straight" was my concern. I know the guide allows for some play but its so important for the alignment to be correct that it simply wont shift into all gears correctly if its off/out. I'm gonna play with it a little... There's not much else I have to do to get it driving so I guess a little trial & error with making a shift rod is my new end to 2020, lol. I have a friend that bought the Naro mount and decided to have it professionally welded in. He hired a welder out of the Portsmouth Naval Shipyard to do it. When done, it was too low for the tin to line up and the shift rod didn’t clear. Welder builds Submarines, so I found it hard to believe he installed the parts wrong. Took some serious modifying to get it to work... Yea, I think the consensus is the Naro mount, when welded in as instructed, is simply not right. It sits too low for the engine tin to mate up to the rubber seals and it causes interference with the shift rod. I'm bummed but I'm not taking the engine out to re-weld it 1/2"-3/4" higher. I dunno... maybe I will. I hate that it is so off. Very disappointed. |

Race cars sure no problem but street car with heat, engine tins that should seal are a no go.. Again I do have a fixture to make this work out of a 4cyl side shift rod if anyone needs one done let me know. |
