If you are not comfortable with this level of work, it is best to have a professional mechanic do it.
Should I buy a Dorman or Spectra oil pan?
Both are reputable aftermarket brands. Some forum users have found them to be nearly identical for certain applications. Dorman has a reputation for its "OE FIX" parts that sometimes improve on the original design. Choosing based on price and availability is a reasonable approach for this part.
