Hi Craig.
First off. There is no such thing as a stupid question. Best to ask rather than chance nd mess up.
1) I think i know the one's your refering to. These I think go into the chassis at the bottom of the rad. There's two tube holes in the chassis. These go in here. Does it look like this?

2) They should be the right one's. Have you pressed in the metal inner's with the lube?
I needed to use a rubber or wooden persuader to get the bolts in.
