Re this product-What's the coating and warrenty period. Do these fit on a 289 CUI motor with an Automatic Over Drive transmission from a later model. The AOD is wider than the C4 and C6 models used during the mid-60s. Thanks-JM

You inquired about our headers under part number 9308403 which fit the 64-73 Mustang and these others listed below: Most 66-73 Fairlane & Torino Most 66-73 Falcon & Ranchero Most 66-69 Comet They work with floor shift models only whether stick or automatic and the automatic versions are the C4 and C6. If your transmission option is considerably wider there is a good chance you will have problems. I know they fit very tight and actually have had customers relay that they need to do a little alteration for clearance. The coating is warranted for the normal year but if you have a lean running condition where exhaust gas temperatures exceeds 1200 degrees it is NOT warranted but can be re-coated for a fee. A lean running condition sees temperatures reach 1700-1900 degrees which ends up with a glowing orange header that NO coating will handle. You may want to check with Pertronix the manufacturer for your clearance questions for additional verification. Their number is 909-599-5955 and their part number is H8403. This is the same header offered by Dougs, Hedman, and Patriot.

The tubes on these headers will interfere with the column shift linkage.
