| Post subject: | Where to connect the LCB clamp to remote gearbox |
Perhaps no surprise that I'm in the middle of replacing extractors and exhaust... but I'm a little stumped as to where and how the clamp on the extractors connect to the gearbox. My gearbox is the remote type, and I have hardy spicer joints. The extractors are brand new generic 1.75" LCBs. There's a clamp (C-AHT98) with a tag.. but not sure where it should bolt to. I've been looking high and low, but cant seem to find any info. The only reference I could find in printed material (workshop manual, haynes, vizard) is in Vizards book and he just talks about how important it is to secure! |

It bolts to the lower side cover bolt. Twist the flat bracket if needed. |

Word of advice - though I use my car for competition so it may have a harder life than yours I've found it waaaayyyy better to make a 5/16 UNC stud (a bit of allthread), screw it VMinto the diff/gearbox housing, put a nut on it, then the exhaust bracket, then another nut - your gearbox casing threads will thank you |

I had a set of long 3-1 extractors that picked up the bottom bolt, similarly with a sonic lcb system. Always came loose and eventually flogged out the thread. I’ve helicoiled it this rebuild and using the above bracket with a maniflow stage 2 lcb and will adjust the bracket & clamp to suit. At least this time it will have 2 points of support to spread the load. |

Mine have thread inserts now too, and studs, and a 6mm bracket that picks up 3 of them - I got really cranky with it and over-engineered |

I have tapped some stripped ones out to 3/8 UNC that's harder to strip again. |

Thanks everyone for all your help and suggestions.. very much appreciated. I located the bolt hole in the remote gear shift housing, which is where the factory manifold bracket/clamp was apparently attached. The thread is 1/4 UNC. Also attached is a pic of the clamp bracket that was sold by Mini Kingdom (thanks John / Origmini) Unfortunately though, the bolt hole was broken and couldnt support any tension... so planning on taking your advice Simon and making up a stud to fit to the diff housing and connect it to there. Will post pictures once complete. |

The extractors in the photo had a bracket to be bolted to the lower side cover bolt. Didn't like the idea so I welded a small tab to the extractors and bolted it to the bolt hole in the remote gear shift housing as shown in Barkfast's last photo. |

Finally got the exhaust manifold and the rest of the system installed. I took Simon's suggestion of using a stud (made from a 2inch bolt) and installed that into the diff cover. I then fitted the rest of the system before making and fitting a bracket. Seems to be ok - but havent started the car just yet.. waiting on some bits to finish the new carb install. |

Turn the clamp at the end of the collector joining the intermediate pipe around so the end of the ubolt is not hanging down |

Those ubolts always catch on a trailer or ramp etc, a PITA. |

I made a strap clamp from 25x3 flat bar, with a bolt at the 9 o'clock position. Better ground clearance and no U bolt to hit. Similar to what my Fiat 124S coupe had. |
