Is it the same??

thats what I had planned on doing. I am building a 2X3 box tubed frame from the firewall back and figured I can put the axle where ever I want and thought the standard bed would look cool with the extra cab. I just didn't know what the measurement difference was between the two beds. 2" back isn't that big of a move! Thanks mazdaman82

the axle will move back more than 2", more around 8-9"

you workin tuckin?

days today and tomorrow Todd, plus I got a stereo install friday night. : sleepyspeed- thanks for the info on the difference. I am building a frame jig so I will make sure the axle is right. One other question to anyone who has cut the rockers on a mazda, is there anything in the way inside the rockers (any supports or anything).

yes the axle moves 9.5", its the body that gets the 2", the std bed is 2" longer then the ext cab bed( just to look you will not see it) but I put the bed cover i had off a ext cab on my std bed and it allmost did not cover it
