Oil Pan and Rear main parts advice

My tribal knowledge on the rear main says pull the engine. A slant is easy to yank.

Stock gasket for the oil pan. Silicone is worthless unless it's molded in one piece. You'll still have to RTV the corners. Use High Tack on the corks and it won't leak.

I prefer the rope seal on a slant and you can't do that in the car. It's possible to make the upgrade hemi style rear seal work in some instances, you have to verify that the lip of the seal will sit on a smooth surface on the crank. Maybe possible to do this on YOUR back under the car but not on MINE!!!
