914-6 heat exchangers, Can these be saved? Options

[geshaghi]

I have a pair of 914/6 heat exchangers, but the header pipes on one side (I believe it is the passenger side) are thin and rusted through in several spots. The sheet metal is in good shape, and the other side is useable. Given that these original parts are now essentially unobtainium, I'm wondering if repair is possible. Anyone have any thoughts or experience on this?

a muffler shop will stay away from these kind of repairs due to insurance and possible carbon monoxide lawsuit (IMG:style_emoticons/default/sad.gif)
You can always pick up some 1.5"od u-bends and try to find a specialty welding shop that can clean up the metal, and carefully weld new tubing in the blown through areas. Then have them ceramic coated.
There are unknown problem areas inside the sheet metal covers, and with all of this work+ cost, no one will give you a guaranty.
These are still available at the dealer, about $5,000.00 a set. Headers are an option, or I'm sure the big Hershey, Pa. meet will have a good used set.

If you bend up a set of headers in the same OD at the originals, I can have my guys transplant the outer sheet metal. I found a set of inexpensive headers earlier this month at the Phoenix Club swap meet, so there isn't much urgency, but I'd love to have a set of HE's for the second -6 I have. If you know any welding shops around town that might be able to weld some of this up, please let me know. You coming to Sherwood's coffee tomorrow?

Our MSDS race headers do not follow the bends of the oe heater boxes, so even if I sell you a set in 1.5", the fitting of the oe sheet metal will be a Sheet Metal Fabricators nightmare.
Tomorrow at Super Car Sunday , Topanga the 918 is showing up on display , I'm bringing the '59 bug. I'll make it out to Sherwood's one Sunday, he puts on a good gathering !
