i dont know what kind of a arms i should get for my 93 blaster

i have a set of stock upper a arms , otherwise you will find you need to buy aftermarket extended a arms , which run 375-600 bucks for the 4 arms .
 
If you need upper A-arms you have to go with stock, there is no brand or company that makes replacement upper A-arms except for yamaha and OEM stuff.

Unless you want to go and spend the money on a whole new set of arms

Price for stock varies on ebay
