1973 Duster headers

What make of headers fit a 1973 duster 340 the best? I bought my duster about a month ago and the headers are hitting on the suspension on the passenger side. The previous owner also had the front end too low and he had flattened the bottom of the headers on a dip i assume. I am looking to buy a new set and would like to know if there are some that are quality that fit well. I have heard patriot makes some that fit nicely but i thought some members might have some experience with this issue. Thanks
