The civic wagon torsion bars are shorter than the civic hatchback and crx torsion bars. The 4wd wagon has shorter torsion bars than the 2wd wagon.
Airgazm are you positive you need wagon tubes for your mugen torsion bars? I just dont see honda or mugen going out of their way to get a strange part for a performance part. Are you sure that you might not need crx or hatch tubes?
And if you do need wagon tubes are you positive you need 2wd instead of 4wd?
From what other members have told me from measuring cars in the junkyards, the 2WD Wago tubes are the length I need. A member on here told me he had the same problem with his Mugen bars on a 3G and ended up using 2WD Wago tubes to make them fit.
Whatever they may come from, I need tubes that are about 12" in length. My '86 OEM 3G tubes are about 14" in length and are too long for my Mugen bars.
My Mugen bars are NIB and have the part numbers written on them. They correspond to the bars in the Mugen catalog scans, none of which show any differences in length in the ads.
