I know I was able to get Taco drop springs to fit my old 78' Hilux after I cut the one small coil off.
I was once told that MGB coils fit? no idea if its true though. Mine rode great with cut coils, only problem I ever had was the arms hitting the spring cups on hard bumps, we cut 3 coils off on mine.
Mighty Max springs fit with no cutting. The stock springs will give you about a two inch drop. I run a set of dropped mighty max springs.
83-97 Mighty Max. They are Belltech springs. Here is the post I did about them. http://www.toyotaminis.com/forum/suspension-chassis-47/alternative-coil-spring-set-up-7552/
