88-98 headers

i was wondering if anyone, who has a stockfloored 88-98, has put headers on their 350? i just got a set of medium length and they hit the cab, i was wondering if anyone has ran the shorties and had them clear without cutting the firewall? says they bolt to the stock y pipe, so im guessing they have the same dimensions as stock manifolds, which clear on my truck....

i got a set og shortys ..nut havent got them on yet...id like to know if there gona work to...ill lt ya know as soon as i get them on

lets cross our fingers, i just ordered a set of shorties!!
