That is what I was planning on...using the smaller ell for the vent, and I got the longer sweeping ell for the drain.

Some people seem to highly promote a 2" line, but the previous was a 1 1/2" that had tons of rust inside of it, so I would think a new 1 1/2" with 2 cleanouts would do ok.

I just can't replace the entire section, and I can't imagine that it would be ok to have some parts 2" and then decrease to 1 1/2"

Sorry about the confusion, but these 90 and 45* bends are underneath the subfloor and not visible in the picture.

It is the drain that comes from the tub-shower and then connects with this sink drain.

Removing threaded galvanized pipe

Which ever solution you chose, removing the threaded galvanized pipe should not be a problem.

Cut the galvanized pipe within 3/4" from where the threads start. Using a chisel, cave in the pipe just above the fitting, then the end of the pipe will easily un-thread from fitting using channel locks (water pump pliars). Using this method will leave the threads of the fitting intact and surrounding pipe will not be broken, damaged or moved.

btw, this is similar to removing a brass plug from cast iron hub (i.e. cleanout). Cut, drill or chisel out the inside of the brass plug, then cave in the plug just as it enters cat iron fitting.

I hope this helps.
