As Pete mentioned in another thread, you will need;
Brackets, top mount, y pipe, dump valve adapter or recirc + piping.
From this photo you can see two mounting points for the intercooler itself to some form of bracketry - that may or may not be in place on yours - any chance you could post some photos of what you have and what the current engine top looks like? Also I cant see a recirc valve but am unsure if they were fitted as standard in 95
If the brackets are in place see if there is a nut welded to the base - if so this will allow you to try a variety of thread types - I would go with an M12 std which is 1.75 pitch (fine is 1.5)
jfyi M10 std is 1.5 and fine is 1.25
