These are the ones that are on each side of the hood about midway down each side. Are they necessary on the stock hood? Reason im asking is that im taking off my CF hood and putting the stock one back on. Well when we took off the stock to put on the CF we took those rubber pieces off to put on the CF but then realized we didnt need them. Well when we tried to put them back on the stock hood it was difficult and we ended up tearing them up so im wondering if i need to go to Toyota and get 2 more.
