do I have any chance of this oil pan working?

Just use the stock one? If it is not a necessity like an oil pan is I would spend that money on an oil pan. I think you can buy them new from a parts store for like 80 bucks or can prob pick up a used one cheap on ebay or craigslist.

The stock shifter isnt bad. What you need to do is get a new handle for it. The little rubber bushing inbetween the handle and the shifter is what gives it that sloppy feel. What I did was buy a shorter aftermarket handle and put it on the stock shifter. That will give you the feel of a short shifter. I've had mine like this for years and seen much track time with it and dont plan on changing it.
