89 4x4 question....chassis dimentions
 

What was the first year Toyota released an extra cab pick up? and upon production of the extra cab, did frame dimentions change? I figured body mount locations naturaly would change but im more interested in lenth and width between rails. If this info is on this site could someone kindly direct me with a link. Thanx

Not sure bout frane lengths but i do know i ext cab e brake cable wont work in reg cab truck..... i tried, didnt work at all on my 91 pickup
