pressed the ends back on. The front cap doesnt sit as deep as the rear(where filter mounts) but both caps are on the stops of the alignment tabs. Is she good to go?
Back:


front:

 

I've never rebuilt an oil cooler, but my first instincts would be to measure from the mounting holes on one cap to the mounting holes on the other, and then compare that to the corresponding holes on the engine block. If its the same, you're good to go, if not... something isn't right.

 

^logical...forgot my thinking cap today it seems

 

if both caps are bottomed out on the alignment tabs like you say then they can't go an further and are good to go.
