Don't know about "best and easiest" for your particular truck, but, here's a few things learned from my first IFS install(still in process.
If you buy a kit try to make sure the instructions are adequate. I bought TCI, front and rear, instructions left a quite few questions. I can only imagine what comes w/ the cheap ebay kits.
Inventory immediately on delivery. Yeah, I know, a no brainer. I missed the shock bolts initially and have now been waiting a month.
Easiest way to remove rivets is to torch the top off, then air hammer out. If you're careful it won't even mark the removed perch/cross member.
There's a lot of other systems it can/will affect, especially your wallet. Steering column and connection, power steering pump, brackets, other pulleys, brake mc/booster, proportioning valve, brake plumbing, motor mounts, parking brake.
I am not tying to discourage, as other people seem to be, you can do it. Then you will have a vehicle that is SAFE and enjoyable to have on the highway.
Regards,
