Just some basic things you can look for at wreckers to neaten up your hachi a bit.
If your rear hatch struts are broken there are a couple of different Toyota models with the same struts, just check the model code as there are different lenghts that look similar. Getting your struts re-gased isnt that expensive though if there not broken.

The glass covers on the headlights are the same as on a few different same generation Toyotas, not sure what models.

Same goes as above parkers and indicators, may be slightly different to line up screws, havent checked yet.

Same goes as above for seat rails.

Theres a heap of interchangable parts between the Toyotas, if your after something specific just go to a wreckers and have a look.
