I have converted my 65 Notch to IRS and the biggest >problem I ran into was the rear engine mounts. <snip> I, too have a '65 notch that I converted to IRS and front disks, about 8 years ago. I bought two brackets from a VW parts supplier, that the trailing arms bolt onto. These brackets are welded onto the swingaxle frame. The brackets look very similar to what is already on the IRS rear subframe. I had a complete donor '73 squareback, so I used brakes, transmission, swingarms, brake lines, bolts, axles, . So I kept the swingarm rear frame, which I believe is more rigid than the later 3 point engine/trans mounting anyway, and did not need the engine mounting rear crossmember. My memory is failing me, but I am sure I used the nosecone of the swingarm trans, and put it onto the IRS trans. I used the squareback torsion springs, with the late style dual springplate's, and torsion covers. There was some compatability problem between the swingarm torsion spring and the later spring plate. This took me several days, mostly, several days of thinking rather than doing! I do not know exactly how to position the brackets onto the frame, but I kept clamping, then measuring, and measuring over the full suspension travel. I had the complete donor IRS, with which to compare, and made it as close to that as I could get. I wanted the tried and tested VW suspension geometry. So, of course, I believe that if you want to go to the trouble of converting to IRS, using the swingarm frame as a base makes the neatest looking, and most rigid rear end. Also, the best thing would be to buy a complete IRS rear as a donor for parts, because you will use most of them! Include an IRS trans and axles/cv's. The engine sits about 15mm further back in the engine bay now, but I suspect this may be in the later style engine case or fan housing that I put in at the same time, rather than in the IRS trans or suspension. It made things a little more difficult installing the engine. My '72 squareback, which has had a variety of big engines in it over the years, suffers chronic cracking around the engine mounts on the body. I have seen other T3's with this. Mine really only started cracking after it was slammed from behind (and repaired) by a careless individual. But I have seen other T3's with big motors do the same that have not been pranged. I would be curious to hear from people who have experienced the same. I did put 4 lengths of threaded rod through the engine mount bolt holes the ones between the mount and the car body) and then through the floor in the luggage compartment, reinforcing it with steel plate, but it kept cracking! ------------------------------------------------------------------- Too much?
