lee, I have tracings of syncro and lt arms. I shortened the bottom of arm into bracket so arms are vertical instead of sticking out. Remove drift pin in bottom arm in bracket, work off of arm, cut 61mm off, sand/file to fit back into bracket, align bracket with arm on van to be sure, drill using bracket to index bit, and replace drift pin. Lower brackets are same casting, but syncro has wider mounting holes then lt. Top base/bushing is different... and think bottom base/bushing is too, but if not available, not a big deal. Syncro ones have some extra tapered thickness to match angle/space between body and bracket/retainer
thanks lloyd, but the lt`s fit fine with a small tweek. i`m not going to try and create a syncro copy arm i just need more rear view and the ability to fold in with out fear of breaking the mirror.
i`m sure they`ll be handy for hanging the drying line on too
