I have a 1989 Dakota convertible with the LA V-6 and would really like to put headers on it as well. I have built several sets of headers, but my issue is since it is a 4 wheel drive the room even with a V-6 is really tight to get by the transfer case and front drive shaft, with dual exhaust. Plus, to make things even worse the local parts store does not even have a source for the stock type exhaust system. So I just left the stock manifolds and built a custom exhaust from the cross over pipe back.
