340 in early abody

S-A63LA. Go to Layson’s website look up 66 dart conversion mounts this number will come up
Got it. thank you! in the descrip it mentions using a V8 kmember & with the V8 & /6 kmembers being the same is this a non issue EDIT I found the page with all of the kits & on the s-a63la descrip it does say /6 or V8 kmembers so its all good. thank you again
