Outer Limits 4x4 Board

Can any one tell me what the standard ride hight of a 1981 MQ short wheel base is? I am looking at getting new springs but no one can tell me the hight it will be. I would like the distance from the centre of the axles to the bottom of the wheel arch. If any one could help please.

Guessing thats its about 15 inches from hub to fender with a seat height of about 34 inches based on some I have seen with stock springs
