How screwed is my K-member?

-
Looks like the 70-72 K member in that ebay link I shared passes the sway bar through the same place as the 73+ but I could be wrong about that. If there are upgraded biscuit mounts that remove the risk of flopping, perhaps I should grab that one off ebay and hope it's good.
 
My thanks to Jim Lusk who is the K-Member guru around here, especially modifying a stock spool mount K-Member for a big block!
And I agree, the factory welds usually are terrible throughout the years.
I applaud you (the OP) for making the post about your problems with your K-Member with detailed pics.
Truth be told, I am a journeyman welder that knows a thing or two and has modified/reinforced several K-Members over the years...
That being said, I really prefer the '73 and up spool mount K-Member over the '72 and older puck mount ones. They seem like a stronger design.
But, The puck mount K-Members are good as well... as long as you use a torque strap on the driver's side.
Do what you need to get your car on the road whether you fix what you have or use the older puck style...

The K in that link has been modified. It appears to be a 73+ K frame that has had the engine mounts added, probably a /6 to V8 conversion.

67-72 K’s are closed on the bottom.

And other than the sway bar tab location, 73+ LCA’s are the same as 67-72. Maybe even 64-72? I’m not an early A expert.

all the 62~76 arms interchange with the difference being in swaybar tabs.

there's granular differences like the stamping ribs in the arms or bump stop shape/height as well as mounting pin, but physically they're all identical and will slide right in.

That one is an odd duck! Doesn't look to me like the biscuit mounts were added (not arguing, just a comment) but the bottom is certainly a '73+. Weird.

Seems like $400 is steep either way. But I haven't been looking for one in awhile so maybe they have gone way up?

Makes me think the '73 /6 K-frame I pulled out of my G3 swap project car is maybe worth holding on to.

Ok, I thought was weird too! It does look like factory welds. Perhaps this was from a car built for a non-US market? Only thing I can think of, but it does make me weary of dropping the cash to get it since it could be Franken-member.
Of course when I first looked last year there were 73+ kmembers all over the place, not now it seems :(

Yeah the quality of the factory welds certainly makes it difficult to tell if something was original or added, it's probably harder to lay down welds as bad as a factory did than it is to do a better job. Something about the engine mount and bracing on the drivers side just doesn't look right to me, but yeah, consistency was not a big thing for Ma Mopar.

There's no part numbers for anything like that, so it's not an export market thing. If anything it may just be a late '72 or VERY early '73 K member, so either they ran out of the '72 bottom halves early or ran out of the '72 top halves late. Ma Mopar is infamous for using up all the old parts on a transition year. If it's factory that's what I would bet, either very late '72 or early '73 causing a mix match of parts.

As for the price I think the $400 is probably pretty reasonable for eBay. Seller doesn't seem to know it's weird and again, it might actually be factory. The welds between the top and bottom halves look original, if anything it was an engine mount swap but yeah, maybe it wasn't!

$1k is crazy. Even the big block K's don't get that. But $300 or $400 for a V8 K, especially on eBay, makes sense. At a local swap you could probably do better but with fees and junk I get it.
