Can anyone tell what the difference is in a '68 K and a '70 K and the LCA's ( Both with sway bar tabs). I am doing a drum to disc swap and was suggested to switch to a '70 k and LCA set-up for ease of parts finding and not fooling with brake hose issues. Here is a link to my thread I started Drun to Disc Thread I have everything now to put my suspension together and brakes except the hoses. If I decided to go the '70 route can I use all my suspension parts?? I would appreciate if anyone can help me on this!! Chuck

late 1966-1969 have sway bar tab on shock bolt mount for front mount sway bar,1970 has middle mount tab for sway bar goes inside k-frame. hope this helps
So I would need to use the 70 LCA's on '70 K frame correct? I couldn't get away with using the 70 LCA's on my '68 K?
I want to run a sway bar and not fool with the sway bar to caliper interference.

Did this brake swap on my 69 bee. Used the 70K frame and LCA's and a firm feel front bar. I'm happy.
Is the 70 K different from your '69, I guess you couldn't use the '70 LCA's on the '69 K

Your headers will fit, it's worth doing...
70 K complete...
not if your car is a factory sway bay 68-69 performance car, not a a/c sway bar car. it would be mutt job, what would you be gaining??

The late style disc brakes fit properly without rear mounting them... If you front mount the late calipers they hit the early type sway bar.. Many simply rear mount the calipers but when you rear mount the calipers the brake hoses no longer cross the centerline of the steering axis... Crossing the axis minimizes the likelyhood of excessive strain on the brake hose from steering motion... Lots of guys do it, but look at any factory engineered car & the hose will cross the axis.... You think thats just a fluke?

[/quote mostly right, most have failed rear mount by dart calipers hiting shock bolt,hoses too short,hoses rubes on lcas,hose pinching on turns, if you have an a-12 car or 66-69 hemi cars you want to retain the correct stock k-frames,and sway bars, not barning 1970 k-frames into every thing. ive made my brake kits work mint with all mopar parts and the better i think pin type calipers from 1973-78 mopars much stronger mounting.and also with the large pin type caliper adaptors can go up to police 11.75 from 10.75 discs, also have my kits on my race cars stops mint @ 100mph plus in 1/8 drags with no shut down at my track and right angle turn and the end many car go in the woods every year that run slower. if you cant figure out how to right with factory parts, theres many kits out there that go right on your drum spindle done deal no quess work
