Can anyone give me any helpful hints about fitting a rear box to a Mk2? Also do I need to buy a new gasket or anything to fit it? (3/00)

Probably don't need a new gasket for the Mk2 yet, but they're only a couple of pounds from Mazda, so worth having it spare, just in case. You'll find soaking the nuts attaching the back box in WD40 overnight helps. Soapy water is great for getting the exhaust hangers off. Watch the positioning of the tailpipe in regards to the rear tow hook bracket; larger bore pipe can foul on this, and aftermarket boxes tend to heavier than stock, and s the standard hangers can stretch (hence the box can move around a bit). Some use uprated rubber hangers to fit, but nylon straps wrapped around the hanger (squeezing it so the exhaust is pulled up) works well. Replacement hangers from Mazda are pricey at about Pds8 each, but they shouldn't need replacing yet. (3/00)
