Ah! Thought I remember you selling the Doug's headers right after you got them but wasn't sure. Try motopsycho, says the housing for sell he might have all the parts to get a complete one for you.
yea, i did sell them right after i bought them!.lol cause i got a set of hi-pos for the scamp. but decided against using the 72 340 manifolds for the duster, and picked up the used set of dougs for 300.00 off craigslist . so all i have now with no use at the moment is the 72 340 mani's
