Dash Question

What all would it take to get an '01 GMC 1500 dash into a '91 GMC truck? Both Fullsizes

btt
help!!!

ive done the 95-98 dash in a 91 but i dont kno bout the late model dash. youre probly gonna hav to fab up some mounting brackets, and the a/c ducting. and figure out someting with the gauges,,, i juss used autometers... thats gonna be a huge job good luck!!!

i have disassembled several of the new style dashes. will be lots of work.. the new dashes have a million bolts holding it in verses the 10 or so holding the older style in. can prolly be done but it will take lots of time.
