I'm Afraid

The way i look at it, we all have bitten off more than we could chew at one point in our lives, but that is how we learn.
Prepare yourself with the tools that you will need and most importantly, a Factory Service Manual specifically for your car. Read the FSM front to back on the topic at hand, and if you are careful,you should have no problems at all.
I say do it!
Just my 2 cents as usual,
