I need to rebuild my transmission so I might as well reseal my 1958 365 motor with some fresh gaskets.
The motor is leaking at the oil pan and front/rear seal.
I can order the compleet Felpro gasket set but is this any good? Or are there better options on the front/rear seal and gaskets?
I really like your guys opinion on this.
Many thanks, Ramon

I would prefer the kit from Best Gasket. Terrill Machine is selling that kind of gaskets. More expensive than Rock Auto, but I had some disappointments with Felpro.
FYI: Felpro valve cover gaskets aren't thick enough compared to OEM. There's work arounds, but best to find the correct one.
I believe, if I understand your terminology, the front and rear shaft seals are rope, not gaskets. So need to know how to replace those. Others here have had trouble. My rebuilder used modern sealants with the gasket set to get it leak tight. Trans not so lucky. Different mechanic.
Lots of this info is available through the '58 Cadillac owners club. I don't visit there, anymore due to internet security issues. It was on facebook and yahoo groups, last I knew.
I used a Felpro kit for my 57 365. Mine came with split rear main seals, no rope. It will leak no matter what seal you use if your crankshaft surfaces are scored so you might look into getting some speedi-sleeves along with the gaskets so you're ahead of the game if you need them. It also came with two different sets of valve cover gaskets, a set of thin and a set thick. I used both thicknesses (had to remove the covers to diagnose a ticking and oil burning problem), I didn't have a problem with either thickness gasket but I also use shellac on all my gaskets.
