It was a pain in the rear getting the nuts off the stems from
underneath, had to get a deep socket from the auto parts store, but
now everything is disconnected.

But the faucet assembly won't budge. I've pulled from above and
hammered from below. What do I try next?

It looks like the new faucet assembly will go in easily once the old
is off, but I can't seem to get there.

Help!

thanks,
