Questions re: 300TDI radiator/intercooler in NAS D90

I'm in the middle of a conversion to a 300TDI from NAS 3.9L V8 (anyone needs some V8 parts?) and the radiator/intercooler assembly seem to mount too high in the front of the engine bay. See attached (white D90).

The combo rad/intercooler fit perfectly in the NAS radiator locating holes but it just sits too high. Aside from hood clearance issues and the fact a good 1.25 inches of the radiator are above the air inlet of the grill, the engine sits way too high in the compartment in the front in order to match the shroud (centering of the clutch fan). Also, the radiator retaining 'straps' which hold it in place/down aren't even close to reaching the top of the radiator.

By contrast, I've looked at photos of other 300TDI D90s on the list here and this does not appear to be the case (see attached, green D90).

The NAS radiator sits up on two pedestals which have the locating holes (and rubber bushings) in them. I had the thought to either cut these off completely (would cause other problems and probably drop it too low) or cut off the top 1.25" (or so) and weld a plate/drill a new locating hole which would locate the radiator lower. But, then I thought, do I have the right radiator/intercooler combo in the first place?

Another wrinkle is that I have A/C, and if I modify the height of the pedestal mounts for the radiator I'll have to modify the mounts for the condenser as well (and perhaps the lines...)

What have other guys done?

I shorten the frame mount height and re-weld. Takes 20 mins.

@Barry - yes, I'm going it in San Pedro. You are welcome to stop by - I'm out of town for work this week so I won't be getting back to this before the weekend. PM/email me.

@Doug - that's what I was thinking, but then I also have to lengthen the condenser mounts the same amount I shorten the radiator mount so it all still bolts together. It'll take me longer than 20 min, I'm not a good welder ;-)

Why is it up so high? I have done several conversions and never saw the rad sit like that...

If you never had this issue, then that's a great question. It seems like Doug has seen this before.

There are two raised pedestals/mounts welded to the truck frame front crossmember formerly holding the bottom of V8 radiator which this 300TDi radiator/intercooler assembly fits perfectly into (the guide rods that stick out of the bottom of the radiator frame go right in) - however it simply sits too high.

Either I have to cut them off and make them shorter (per Doug's suggestion)... or I have the wrong radiator/intercooler assy? Not sure...

------ Follow up post added June 28th, 2010 06:19 PM ------

PS Randy, you don't happen to have any extra 300TDI radiator straps which secure the assy from the top, do you? The V8 ones appear that they will not work, even after I manage to adjust the height.

The v8 straps will work, they're just not quite right.

I also can't offer any help on the height issue, since I used a 300Tdi frame.

@Randy, part # appreciated!
@DB, from an unknown donor vehicle :-S Taller might make better cooling? (optimistic!)

Discovery radiator IS taller than a defender type.

Not sure how the lower frame mounts differ between V8 & Tdi... can't remember what my Tdi ones were like now, but i think they were lower.
