Seats are a fairly easy swap.Never done a dash swap but others on here have so they may can help.It is a bioutch to get the Mazda dash out to do a swap,that much I do know.BJ
Really - I have the same seats and they bolted right in - I did it in the wreckers parking lot - well after I went back in and swiped a couple more bolts <img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D -->
i put 1992 mazda 626 seats in my 1991 B2200 they did not bolt directly in i think it is because they were to new but i fabed brackets out of 3/8 inch plate steel. check out the cardomain link for some photos.
