I just ordered one recently from Bob in upstate NY for my lil indian 71 saber project. He claims to have thousands of parts for Lil Indian and other brands. I paid 85.00 for it. his number is 315-689-7047 or
mbman@juno.com. He was very helpful. Whn I installed it - needed to use some extra spacers on the bolts to keep it leve- the extra pint on the frame caused the caliber to slightly out of alignment to the sprocket. Hope this helps.
I am looking for in good condition the handle bars and hardware for them if anyone has some out there.
Will post my MB pix soon. Thanks, Bill1
