as you have purchased the lwb chassis then you could just swap the chassis over and eveything will fit ok but it will have the ftx blaze short wheel base instead of the shark which has a slightly wider wheelbase, also you will only have 2 wheel drive, see below:
if you want it the same as the shark you will need the:
front lower arms,....... lrp112505
front upper arms,...... lrp112504
front knuckles, ........ lrp112503 or alloy optional ones
rear lower arms, ...... lrp112506
pivot balls for the knuckles,

or these titanium ones that will last a lot longer,

front and rear shock towers, optional,

also if you swapping the chassis over you will need to buy one of these or you will only have 2 wheel drive as the chassis is 25mm longer and as such the centre shaft has to be 25mm longer

and one of these to strengthen the 25mm longer chassis,

get them while they are there or you will have to pay a lot more new,
ps: no they are not my parts and i dont know the seller, just did a search..
