Hi Steven
1 The arms are handed but never the same when put on a flat
surface so you need to compare them so that they are the same angles
2 Standard are ok but they need to be modified for my special racks
3 Standard racks are 47.00 Quick racks 63,00 the very special shortend
quick racks kits are 280.00 (this inc. the special track rods and rack
mount kit)
4 Solid rack mount kits are 22.50
5 Just ask I`ll supply you with everything you will/might need
on you tvr
