Slant 6 6 into 1 JR/Mopar Performance Header

I bought this header with some other slant performance parts as a package deal and was thinking they just might fit my early A 65 Dart wagon. It had no identifying marks on it other than 9471 stamped on the flange. I thought they might have been Hookers; however, I now believe they are an older JR/Mopar Performance 6 into 1 header with a 3 inch collector. I found a post on slant 6.org where the same identical looking set was installed in an early A. It was not a drop-in as several tubes had to have strategically placed dents here and there. See this thread:

I suspect it won’t easily fit in an early A with power steering, which my wagon has and can’t be changed (it’s a wife thing!). I think it would be a better fit in the 67-76 A Body with or without PS rather than in an early A but that’s just my opinion. I have found a set of Clifford long tube 6 into 2 Headers that DO fit the power steering in the wagon so these are excess to my needs. These 6 into 1’s appear to be pretty much NOS and have never had any exhaust put through it. It does have header wrap on each tube extending from the flange to about a foot and a half or so from the flange. $300 plus shipping from 22657.
