Just trying to help pass along some info to my fellow Mopar nuts
These headers are built by Harold Johnson. He can be reached at 479.474.1551 between 1:30 & 9:30 central.
These Headers are hand built by Harold Johnson, owner of Spitfire headers. They are in a test and developement phase at this time, however, they are in production and have been redesigned (see above pic). The collectors no longer look like the ones pictured in the links below. Harold is a one man shop for the most part and production times vary. There is a long waiting list that gets longer by the day. Although shipping times have dropped (some as little as 10 days) Do not expect that you'll get them any faster and it'll be like an unexpected Christmas when they show up at your door. Try to plan ahead and get your order in waaaaaayyyyy before you think you'll need them.
These headers started out for 63-66 Mopar A bodies without power steering. The engine compartment in the early A's is about two inches narrower than the 67-76 A bodies and is extremely tight on the drivers side. During the early test sets, Harold found that the headers were a fairly universal fit thanks to his tight tri-y design and the collector exiting above the torsion bar. They will fit 63-66 non powersteer cars, 67-76 manual and powersteer A bodies, and he claims B and E bodies as well as trucks, as long as they are small blocks and use an A-body 90 degree oil filter adaptor.(I have no way of confirming the fit on anything other than an early A body).
There have been some problems with 67 up A body 4 speed z-bar clearance.
The pics that follow are of an early test set on an early (63-66) A body. Any problems I had with installation were reported to Harold and was supposed to have been corrected.
Harold is currently producing a 3rd design and possibly working on one that may fit the 63-66 power steering cars. Keep your fingers crossed.

I didn't want to load up this page so click on the links below. I kept some of the image sizes pretty large so that they would be really good quality, but they might take a little while to open up.
