Inliners International Forums General Discussion Engines Three 292 questions

As I get closer to putting my motor back together, I'm trying to get this stuff sorted out.

1) I have 2 different T-Stat/by pass fittings (?) On one, the by pass hose is like 1", and the other is more like 1.5". Which one of these is better to use?:



2) Does this bolt go to a 292? I can't remember taking one out that looked like this on the 292 I pulled apart. This was in the basket case 292 I bought:



3) One of these oil pans came off a 292 in a '69 Chevy 4X4, and one was from the basket case, and I forgot which was which. The only difference seems to be an indentation at the rear and a slightly different baffle plate. Which would be best in a '68 Chevy 2 WD truck?







Thanks, guys
