It's really not that bad, pretty straight foreward. Basically, you remove front seats and carpet, drill holes, bolt up, re-install interior.(sounds so much easier like that doeasn't it! LOL)
Allow yourself 2-4 hours (depending on weld in or not, facility, tools, help, skill level...) the 1st one will be the hardest, it will get easier and go faster and faster after that.
Here are some pice of various steps, I have more but need to find them.
Okay, here is an interior shot where you will need to clear to drill.
Watch out for the Wiring harness!
Move harness away for drilling clearance
Remove parking brake line retainers. You wont need them, so just break them off with a hammer and scraper.
Scrape away any seam sealer sticking out so they sit nice and flush
Position subframe connector located to install position to mark holes. On drivers side, carefully slide it behind the brake lines
Jack the subframe connector up into place
Mark all holes to be drilled
Remove the subframe connector so you can drill out the holes. Use a center punch to mark the center of the holes
Drill out all holes using a small pilot bit 1st, then step up to the large bit.
You will most likely need to scrape a little of the sound dampening material away.
You can spray a little primer on the holes to help prevent corrosion
After all holes are drilled, re-position the connector to be installed
Bolt them all up tight. It helps to have someone help by tightening from the top.
Re-install interior and you're ready to go for a spirited road test!
