I posted on zcar.com and got this answer. Anyone agree/disagree? "The old steel sleeve has to be removed via cutting, the new one is pressed in, and the edge is curled over using a special die and a press. Or a big hammer can be used to peen it over, although it tends to tear the edges. A good machinist can cobble up an effective die pretty easily, it's a simple shape. If you look around enough you might find one of the guys who has built his own die and will let you borrow it." What's weird is the 1971 factory Nissan shop manual doesn't mention anything about special tools or reassembly other than a drift set part number ST33260000 to remove the insulator. |

Hey SurferD, The factory installed the bushing by peening the end over so that it cant be removed. Obviously you cant install a new one using the same technique unless you have special fixturing and a bid press lying around. The bushing is made of three pieces; inner sleeve, rubber, outer shell. I think the poly bushings are made to install into the original outer shell where you remove the original rubber by torch or other means. The replacement that you have appears to have the same 3 piece design as the original. So that means you 1st have to remove the inner sleeve, get all the rubber out, and also cut out the outer sleeve. You should be able to use the replacement without peening the end over, as that big washer with the rubber insulator holds everything together anyway. But you may have to cut part of the sleeve off (that you didnt peen over) so it doesn't interfere. By the way - I should still have a 'stache bar sitting around with the original bushing already removed, to save you the work. By memory, I removed the outer shell not realizing you are supposed to leave it in when you go to poly bushings. If you are interested I'll scout around for it. It'll be CHEAP. Tim |

The original metal bushing retainer stays, and the new ones go within the old metal retainer. It's a 10 minute job.....stick one end in fire.....heated up real good. While still hot run a wire brush on a drill to clean up better, stick new bushing in while hot, stick in bucket of cold water. Trial and era.......don't do what I did once and throw the whole mustache bar in the fire......it will warp like hell.......just the bushing end. |

I decided to just go with poly anyway. So I'll have to cut out the steel bush and rubber and leave the shell. Thanks for the replies. |

I started using a sawzall to get the rubber out. It wasn't working that great. Then I spotted a 1 3/4 hole saw in the toolbox. Viola! they both were out in less than 5 minutes. I used a propane torch to soften then scraped the rubber. Finished off with a 2" coarse wire wheel to get residual off. I put some paint on and now everything is set. |
