You have to start by pulling out the transmission, this will give you access to the rear cover of the engine, and the rear crankshaft oil seal. You have to remove the rear engine cover once exposed, then you can pop out the old seal and press in the new one! And re-install transmission.

How difficult is it to change 350 main bearings in chassis?
I assume you mean to ask how difficult it is to change the main bearings WITHOUT pulling the engine out of the vehicle. Don't bother. To properly replace the main bearings you need to pull the crankshaft away from the engine far enough to be able to put a micrometer on the bearing surfaces of the crankshaft. To do that you need to disconnect the crankshaft from the transmission AND pull the pistons part way out. Also, depending on the type of seal used, many rear main seals must be replaced by pressing them into place after the crankshaft is in. Don't even try to replace bearings without first verifying the status of the crankshaft. It must be round and within tolerance. If the old bearings have worn there isn't much chance that the crankshaft hasn't been affected.

Can you reuse your crankshaft after breaking the main caps?
If you are working on your main caps, then you are in an engine rebuilding situation. If they actually broke, you need to find out why, and replace or repair the parts, including the crankshaft, that are bad. If, by breaking, you simply mean that you loosened the bolts, you still need to evaluate the status of the crankshaft and bearings. This involves checking for size, remachining as necessary, replacing parts as necessary, checking bearing clearance, and torquing the cap bolts to specification.
