You can get a rack for around $100
$700+ for parts and labor is WAY too much...our racks are easy to R+R, if you have any knowledge of lefty loosey, righty tighty, we can walk you through it
note that Gen1 and Gen2 Racks are different...best rack for a gen1 is a 93, Gen2 = 98 ( if you get one out of a salvage yard)
As far as alignment, just count the threads as you remove the inner tie rod ends...make sure you remove the boot from the ends of the rack, which will expose the nut end of the inner rod, remove the safety pin from the inner tie rod end.
If you have trouble with the outter rods, just smack the knuckle where the joint is with a hammer, it'll pop loose
edit: just called Advance..I can get a 93 rack for $72.74 with exchange $20 core
94-98 have same part number ..$87.29 exchange, $20 core
my labor book shows 1.5 hours...
You tell me where the extra $500 for Sears is going
