plan on about 1 hrs to get the old off if you have a sawzall
and then allow about 2 hrs putting the new one on and getting it adjusted so it doesnt touch the frame and firewall
good rule if thumb is to lay a 1" 4" acroos the tranny crossmeber and let the new down pie rst on it while you adjust and tweak the rest of the install and then after its all done, go back up and tighten the outlet pipe clamp and then remove your 1x4 and go for a drive
its reallly really easy
you can do it, save your $$$ and do it yourself
