Is there a Bolt-on hardtail commercially made for a Triumph Duplex Pre-unit frame?

Dosen't David Bird make them?...Or, does he only do single loop frames?
My first thought was Willy J, but I don't think hes done anything in awhile,..

I know Bird makes em for Pre-units (ordered one couple weeks ago.. whoohooo!) but not sure about Duplex. Frames are different right? Duplex has the twin downtube.

I'm sure if you email Tyler over at LowBrow he'll put you on the right....

Good info here. Not sure it's your year though ChoppyGee?

AM I a moron or will a unit style frame hard tail fit the duples? I've been looking at photos in order to do research on this very subject, and I see little difference between the mounting points for the rear subframe on the standard 64-70 unit frames and the 60-63 pre-unit duplex frames.

I realize there's obvious differences in the swingarm mounts and motor mounts, but the top and bottom frame mounts look identical. Help!

Thats something I was wondering too Sinner. I'm hoping so, I know where a never used unit hardtail is for super cheap.
