Gussie,
IIRC, the only tools needed were a phillips screwdriver, a razor blade, & a tube of black RTV (AutoZone, Lowes, Home Depot, ACE, ...).
I've done enough of them that 'start to finish' takes about 30 minutes.
A couple of 'nice to have' items are a roll of duct tape in case you tear your vapor barrier & a can of lubricant for the window tracks.
