You could try 48" toyota springs I think the stock Mitsu leafs are around that length. The center pin will probably be way off though I'd measure the stock springs first <img src="/forums/images/graemlins/kewl.gif" alt="" />

79-83 Toyota Rear
Flat length = 48"
Front Half = 21.125"
Rear Half = 26.875"
Width = 2.36"
Front Eyelet = 18mm ID
Rear Eyelet = 18mm ID


84-88 Toyota Rear
Flat length = 48"
Front Half = 20.5"
Rear Half = 27.5"
Width = 2.36"
Front Eyelet = 14mm ID
Rear Eyelet = 18mm ID

The 84-88 spring may fit nicely <img src="/forums/images/graemlins/kewl.gif" alt="" />
