That’s a 411 sss wagon. The RL in the vin tells that. The front brakes you have are not compatible with the bluehands/mklotz g20 brakes as you’d need to source a set of drum brake hubs off a j13 car to fit them. His setup is a drum to disk conversion for rhe pl411, not a disk/caliper upgrade for the rl411.
bit of misinformation on bananahamuk in that the 411sss already comes with a 3.89 rear gear. Anything numerically lower will make it a bear to accelerate, and any numerically higher and it will only do 70mph at 5,000rpm.(I ran a 4.11 h165 axle in mine for a minute)
I highly suggest you join the Facebook 410/411 group. It’s got memebers world wide, and a lot of good info from some hardcore 411 guys. I see it having more traffic than here and quicker responses. On the other hand the Info held in this forum is also indispensable, there’s many write ups and such(I did one myself on how to make a 411sss 4 speed trans out of a roadster and 510/521 trans)
also, that’s my old hood from the day I blew up my car about 10 years ago, i painted it up for the eagle rock swapmeet and spun a bearing then threw a rod exiting the 110fwy to go there. It’s for a 410, has threaded nuts on the hood, later cars had them threaded on the hinges.
