Jack and the Beanstalk

Hi All

Please could you assist me in getting information on the list of sierra parts below. I need the weight of per single item, for import info

My supplier has technical communication problems and difficult to get this info from him

2 x sierra cosworth 4x4 alloy engine mount brackets
2 x sierra 2'9 cast iron 4x4 engine mount brackets
2 x sierra Headlight wiper stopper brackets (this what the wiper rests on)
1 x sierra Gear box 4x4 X- member(steel one that fits type 9) and rubber mount (together)
1 x sierra window front switch (i'm guessing the one by the gear lever)
2 x sierra Rear window switches (the ones that open the rear windows)

The total weight of the package comes to 8.5 kgs. Our trade dept informs me weight estimate can be more not less.

Please advise soonest

Cheers
