I'm wanting some bucket seats to make my 98 rolla feel a bit more mine. But the mountings to the car are a bit odd (one mounting hole is sideways) any cheap(ish) bucket seats that have worked for others? 

Get a set of front seats from an AE101 or AE111 Levin/Trueno, they bolt straight in (just swap the seatbelt buckle over) and are much better than the stock seats.

Much appreciated. I was suggested saas bucket seats too with their *universal* mounting rails. Is it expensive to get custom rails made?  Because aesthetic wise,  i prefer the saas buckets.

There are Bride/Recaro etc rails (both genuine and knock-off) that will bolt in and allow fitment of a bunch of aftermarket seats
