seat install - mounting

[rodstored-72]

hi guys,
well i am going to try to install a late model seat in my 72 2wd swb. i am wondering exactly how some of you guys did it?? i am wondering if you guys like just aligned the seat & then drilled the holes? (& ofcourse added the bracing) i also wanted to know what you guys did about the original holes that may not have been used? also would like to know all if any of the little secrets to installation??

thanks for any help!!
