What are these holes for?

[kevin powles]

Hi, Interesting, I had not noticed those holes before, on the tank hunter the front driver armour piece is off a british carrier and has not got those holes, when I aligned the armour it went in perfect, other intersting note is on a british carrier the dash holes are the same as on a canadian carrier, but the cable armour cover for the headlight utilisers the bottom dash mount hole for one of it's securing holes. On a canadian canadian built carrier there are two seperate holes, hence the inside cable guard cover wont fit, puzzled this one over for an hour until i looked at the uncut mortar carrier and realised the difference.

does this make sense, not saying all british carriers dont have those two fuse holder fuses but i think Mk2's dont?.
