$315 this includes everything needed to install into my car. The gauges were 272 USD by themselves, they are prosport evo series metric. I like the look of them, check them out on youtube :D!

How do the gauges fit when their diameter is greater than the din height?
 
Cheers

the gauges are 52mm in diameter, they fit fine into the din holder i bought for them. How big did you think they were or were you making a different point? I'm confused.

Example
 

That fits well.  On the gauge I have (autometer), the outside diameter of the bezel is a a couple/few mm more the the height of the din.  so it would stick out beyond the holder that you have, and over the plastic piece of the car (the din/ashtray/vent surround).    Looks like the autometer ones are on the large size (even though they are classed as 52mm) and wouldnt fit as well as yours.

Yeah those gauges arent the ones i bought. But i test fitted mine and they are all good to go. 

I also bought some ebay radiator hoses, they aren't as bright blue as they appear in the photos, They look quite tough so I am happy iwth my purchase $60 not bad.

$60 bro that's dirt cheap last time time I checked it was $80
On eBay they only seem to list 93 to 99 turbo hoses so are you sure these are the right ones?

Even if they are 93 on they'll be fine, I've used them on a 91 3s.

I believe a couple of the hoses are different, for sure the one that goes up onto the thermostat housing would be different.
