1966-1973 Ford Bronco 302 289 Exhaust Manifolds Doae-9431-l & C6oe-9430-f on 2040-parts.com

 Here is a matched original pair of Ford exhaust manifolds for a Bronco. These are correct for the 302 engine but would also fit the 289 found in the early 1966-68 Broncos. Technically, these are date code correct for a very late 1970 or an early 1971 Bronco as they are dated 0 E 22 for May 22nd, 1970 and 0 H 7 for August 7th, 1970. You may have noticed the 1966 Ford casting number of C6OE-9430-F. Sometime in very early 1971 Ford switched designs of this manifold to the more common D1OE-9431-CB on the driver side manifold. They also switched designs of the passenger side manifold from DOAE-9431-L to the D1AE-9431-BB.  The 1970 date codes show these to be an original matched pair even though the date codes are 2 1/2 months apart. It is likely Ford was using up the last of their outdated manifold castings before going to the new designs. These are totally undamaged with no repairs and have been glass beaded and then treated with a manifold dressing to keep them looking new instead of starting to rust again in a few days. You need to handle them with gloves to keep the gray off of you. The first 3 pictures of  are how they look now after treatment and the rest of the pictures were taken fresh out of the glass beading cabinet. I have used this dressing on my personal show quality cars for many years. All studs and threads were checked and they are perfect. The one hex head bolt shown in the 3rd picture is not original and is brand new. Includes correct nuts and original bracket bolt in the side. The heat choke nipple will need replaced - the old one has been removed. There is some pitting around the choke tube area but at least now it won't get any worse. Also included are the original undamaged donut holders that go on the end of the exhaust pipes. All threads and studs have been checked and are fine. These will be show ready after the nipple installation! All casting numbers and date codes are easy to read. I fully warranty them when you get them that they will fit and function as new when used in a factory application. You drop one on concrete and break it - don't call me. There will be a final curing time of a few minutes when the engine is fired up the first couple of times so do it outside so you don't get fumes in your shop. These are impossible to find in this condition/restored with matching date codes!!
