80 dollars an hour is the average shop rate. You can take it from there.
here in GER an hour costs 160¢ an hor at the local jeep dealer.
when i ask themabout a pri´ce they said that everything would take 1-2 hours longer than i needed. and they are professional.
go to your local 4x4 store where you buy your parts and they will make you a good price.
or if ypour friend says he can do it then install it with him.
we can give you good write-ups for nearly every jeep parts installation.
and installing a suspension lift isn´t a magic thing. follo wthe write-up or the install. manual and you´ll do it without any problems.
the only problem with your 97 wrangler is that the bolts could be rusty. spray them with something like WD40 for a week before the installation and they should be no problem anymore.
