I tore apart the brake booster mount for my Javelin to blast and paint. Unfortunately it's in worse shape than I thought. You can see from the pictures that the metal tube insert for the pivot is eaten clean through. There are also nylon inserts that go in there and they're worn out too. (Forgot to get a pic of those). Is there anywhere that sells part to fix these?    |

Found the nylon pivot bushings and booster boot at amark. Guessing I'm going to have to fab a new pivot tube myself to replace that rotted one. Doesn't look like it was meant to come apart. |

It wasn't, pressed fit IIRC. There is no stress on that tube, it's really just a spacer/bushing holder, it's not going to cause any problems used as is. It's hidden, I'd leave it alone, but if it bothers you you might consider grinding it down and slipping a piece of thin wall tubing over it instead of trying to remove and replace the tube. That will probably be a cut off and drill out operation, then tack weld a new one in place. ------------- Frank Swygert |

I have some of these peices. Will dig through and see if I have a good one. -------------

| Thanks, I'd appreciate it. To repair I'll have to cut the bad half off and weld on a new piece of tubing. It's pretty cooked. I could easily crush what's left with a pair of pliers and minimum effort. |

Before I did that I'd glass bead it, do a weld build-up with a MIG or gas torch, and dress it to shape. ------------- Roger Gazur 1969 'B' Scheme SC/Rambler 1970 RWB 4-spd Machine 1970 Sonic Silver auto AMX All project cars. Forum Cockroach |

| Thought about weld/patch as I've had success with other unusual repairs. Maybe the pic doesn't show well, but for this I'd have to recreate half the tube. Then when done the inside would be crud and need a lot of work. Sliding in a half inch bar of brass or copper might do help, but don't have any handy. New section of pipe would be easier. If there's no alternative it will be a weld up job. |

I guessed that the weld repair would be substantial. Personally I would use a gas torch as I have better control with one as opposed to a MIG. As to the interior I was assuming (there's that word again) that since you are using the nylon bushings that the interior finish wouldn't have to be that good. A cleanup with a die grinder may be sufficient. But I'm just throwing out suggestions; you have the part in hand and have a better idea of what is, and isn't, feasible.

If you can't get a replacement, media blasting, welding the holes closed, building up the tube while using a brass shaft as a form inside looks a lot simpler than removing what's remaining of the tube and replacing it. Like others said, a die grinder or correct size mill will clean up the interior. Brass round stock is available on ebay, and not that expensive. Flanged brass bushings are available from Aircraft Spruce and dirt cheap, less than $5 sometimes. They would work as an inner form. ------------- 70 Javelin SST, second owner, purchased 1972 |

| Why are you wasting so much time on a $10 part? Even if you have to overpay for one, it's still so much less time and $ to just replace it. They are not that hard to find in good condition. I see them at shows in people's "junk parts" boxes. If you can wait until the weekend I will get you a replacement for $10 + shipping. Even if I have to send you the one from my own car... |

$10 + shipping? For that I'll take one also. Seriously. ------------- Roger Gazur 1969 'B' Scheme SC/Rambler 1970 RWB 4-spd Machine 1970 Sonic Silver auto AMX All project cars. Forum Cockroach |

lol, I'm just waiting to see what Teamamc finds in his junk box. Not interesting in spending $75 worth of time/effort if I don't hav'ta. I tried to find a whole new booster mount a little while back for a good price. No luck.

I have not been able to locate the peice. I sent 2 complete boosters out to be restored. May have sent the extra peices with it. -------------

lol. the list grows. Unfortunately I'm not able to find a piece of pipe the correct size at my regular local hardware spots. Looking if it can be ordered for something less expensive than the price of a new car. :P
