I don't know why I didn't think of ebay. I guess I was afraid of buying something that didn't fit well. I've had mit-or-miss experinces with some ebay sellers in that regard. But I'll have to comb through there.
No stock manifolds. There are headers on the car now. They are pretty rusted and really banged up. Looks like someone in the past had to dent and bang the heck out of them to get them to fit. I have leaks all over this system from stem to stern, and it's pretty well rusted out. I've been patching it together for a while just to get the car on the road again. But it's getting to the point where I want to finish up the exhaust...among many other things (hence the frugality).
