Hello,

I have ordered a new radiator grille (part number: ASJ710060) , my plan being to drill out the standard lower front aluminium AC grille which is prone to corrosion and the paint flaking off, I'll then replace it with an aftermarket stainless version.

Would anyone be able to tell me what size of rivet is used on the lower AC grille?

Have done some digging around and emailed land rover directly, for anyone interested they are 5/32" x 0.335", part number RA610183.

I am very surprised you managed to get that information out of land rover. I just treat a rivet as a rivet and use ones suitable for the thickness of material.
 
4 x 9mm will offer a tight fit (essential to stop it moving around).
I'd be tempted to fit 4.8mm x 9mm large head rivets (you'd need a good/new 5mm drill to clean up and resize the holes) and some sealant between the alluminium and the stainless to stop any bi-metallic rusting.
That will be the trickest part, isolating the material.
The new grill will look/stay fine and after 2 or 3 years the lower part of the frame will go all white and furry and a year or two on, rot away.

Making the grill easy to remove may be an option, so you can get behind the frame and keep it clean/oxide free.
If you drill/tap the holeson the grill to M5 and then drill the frame out to 5.5mm, you could fit some M5x10mm dome headed set screws (there are some really nice coloured, anodised alluminium ones available, they are used to hold on motorcycle fairings).

Pictures - we like pictures.

If you are drilling out holes to resize etc and making it easy to remove you could drill out and file square to fit RTC3745 (little square plastic locking insert) which you can then use stainless screws into to hold it in place. This isolates the stainless fixing from the aluminium and allows for it to be removed. to isolate the stainless grill I would be looking at putting a thin strip or neoprene tape around the edge so it sites on that against the rad frame rather than directly against it.
