Lower Radiator Support Interchangeability?

Postby Aidan » Sun Sep 13, 2020 1:31 pm

Hello,

Does anyone know if the X300 or X308 lower radiator support panel is suitable for use on a late model XJ40, or perhaps is adaptable to be so? I have yet to invetigate how bad my car's really is - too many other things to tackle before I get that far - but looking at the general condition of the underside and running gear I'm pretty sure the lower radiator support panel on my '40 will look more like lingerie than sturdy metal.
The XJ40 part seems to be NLA from JCP and used ones are rarer than hen's teeth, (X300 new part is £400!!!) so it seems our options are becoming limited. Can one perhaps be made up out of flat stock metal sheet... from the JCP picture is might be possible to fabricate one by cutting and welding one plane at a time, or is it in reality a very complicated pressed metal structural shape? I'm just trying to be pro-active so that I have a solution in hand when I have to cross that bridge.

Thanks,
Aidan

Late ‘40 ie 93/94 and X300 have the same part number MNA4188AA so yes they are interchangeable.

It's a bit confusing, Don. On looking at the JCP website again, they say MNA4188AA is for 1995 - 1997 cars, i.e X300 but XJ40s from 1987 to 1994 use CCC2670, and the parts do look very different on the JCP website. Is it possible that the very early X300s, say only in 1994, used the XJ40 support panel and that Jaguar changed the X300's design to the later part in 1995? So could we find that early X300 panels are indeed suitable, but '95s onwards are different?
If anyone on this forum has broken early X300s, could they perhaps chime in and let us know if that is the case?

I can confirm, same part for X300 and late XJ40 as far as I'm aware. Yours might be super crusty but they can be saved generally. Flat piece of metal welded to side brackets will work just fine, you'd have to just cut some holes
1996, 3.2 SWB X300 - Finally a rust free daily driver :)
1997, 4.0 LWB X300 - Unlucky car.

1994, 3.2S X300 - Accident damaged, October 2015. Gone!
1994, 3.2S XJ40 - Long gone.

They are the same part. If there was a different X300 part ie early and late it would have shown on the JCP page in a chassis number change. Naki has one for sale marked as X300/late XJ40 fitment.

Well thanks for the replies, gents. I guess us later '40 owners are in luck.
