Classic/Antique Car Repair: removal of oil pan, plug drain, rear seal

Question
What needs to be done to remove and replace the oil pan on my 1973 el camino? The engine size is a crate 350  

Answer
Um you have 2 bolts at 1/2 in rear and 2 in front at 1/2 inch the rest are 7/16

Remove drain plug, drain oil, remove filter(gets in the way)
Start at front of pan and undo bolts Pop off pan.

To reinstall reverse procedure only clip the end tabs of NEW!!!! front main seal, goop up with lots of RTV, same with rear seal.
