I did mine with a motor plate but made the plate to take nolathane upper control arm bushes.

Shumacher makes an excellent product. So you kinda know how I voted,lol. The reason I did is that a direct connection K frame might be more of a restorers item IMHO. You could flog it to pay for shumacher mounts and there would be two happy mopar campers instead of one!
 
The homebuilt Direct Connection k-member is still among the least costly of the mount solutions for getting the big block in there. I have been building them for more than 20 years and have yet to pay more than $20 for a wrecking yard "K" and more than $50 for a swap meet part. They (73-76 small block k-members) are getting harder to find, but they are still out there. Schumacher makes a nice product, but I consider them overpriced........
 
If you have to pull the engine more than once a year I would go with the motor plates other wise I just use Schumacher mounts.

Looks like I'm going to build my own D.C. style K-frame. I just picked up a small block spool mount K-frame with the correct BB engine mounts for $20. Thank you all for your impute.

If street driven I'd lean to Direct Connection K frame. You can use the big bolt pattern 73 up disc brakes with factory sway bar setup.

The k-member has no bearing on what brakes you can install......

The trick is the sway bar. If you are a drag racer this does not matter, you don't use one. If you want your car to handle well, you need a sway bar. The 73-76 "A" body knuckles and Lower control arms with the sway bar tabs are different than the 66-72 lower control arms with the sway bar tabs. You cannot mix and match the two systems without losing something.
 
Yes, they are different, BUT as long as the sway bar you use matches the LCAs you're fine. Most of the later k-members need the early mounting holes drilled out, but the location is there because most of them do have the holes punched in one half of the stamping. We have built four a-bodies with the late k-member and early sway bars. I haven't used a late bar yet. There's no trick to it....

That is what I was trying to say, BUT I would not use the new style disc brakes with the old style LCA's. You probably could use an old LCA/sway bar set up with a new K-member but you can't use a new LCA/sway bar set up with an old K-member. Which is what I was trying to say in the beginning.

Honestly I dont see an advantage, or disadvantage, either way. It all comes down to what you have to work with and cost. If you have the slant k-member and and its cheaper than buying a bb k-frame and mounts Id just go with the schumacher mounts.

yup.

There's no problem using the late discs with the early sway bar. You have two choices. Swap the spindles to put the calipers to the rear or run short sway bar links. This swap has been going on for thirty years on early cars with sway bars.

People do all kinds of things. Swap spindles to rear, brake lines and routing? Short sway bar links, lose turning radius? I would not, but you or anyone else can. I don't care. I've been swapping brakes for 35 years, 74 Duster to 64 Barracuda, no big deal...
 
I've only got one last thing to say about this. Your condescending attitude in opposition to things that are KNOWN TO WORK CORRECTLY is not going to help anybody.
