Hi I was wondering how difficult it was to replace to the rearend gears in my four banger. I was going to step them up to 3.73 but I heard it was a pain in the butt? Is this true

You will need to get a master kit from Summit, Jegs, whoever, and have a dial indicator to check the pinion backlash and then spray paint or blueing compound to check tooth face wear pattern. You will also need the correct torque wrench.

Hmmm thanks 2 more questions how much do you think a set of 3.73 gears would cost and what is their availibility?

fully available. 2 ways to get them.....
Summit, jegs, etc. or find a set out of an 88 turbo coupe with a stick.

New gear kits are around $300 with shims, bearings, gears, etc. IIRC
