Hi Bobster -

The manifold is held to the compressor by a single 6mm allen head bolt. You'll need an allen key or allen head socket to remove it.

I can't remember exactly on the compressor - it's either 12mm or 13mm, I think. There are four bolts holding the comp. to the engine block.

You'll find the manifold o-rings have these special little "nibs" to hold them in place. They cost something like $5/each. While convenient, they aren't really necessary - the equivalent plain old metric o-ring will work just fine.

I've done the shaft seal on a 10p15c. I think it took 3-4 hours to pull the compressor, replace the seal, install, vacuum, charge, etc. You'll need a decent selection of snap-ring pliers to do that job. Instructions can be found on the web; I've posted the link here before.
