Is there a MTB handlebar stem with ID of 35mm?

I am trying to come up with a workaround solution to a damaged handlebar clamp on a folding bike. The handlebar clamp cracked along the weld that joined the clamp to the vertical tube, so I was thinking of cutting that clamp section from the top of the tube and then fitting a MTB stem over the tube, which has a 35mm outer diameter. Are there any stems with a 35mm ++ ID as indicated in the photo? Much obliged for your help.

I doubt you'll find said stem. But there are still other options. First is whether a quill stem might be able to be used. If so what's the steerer's ID at the top? Next is a custom stem. There are some here, or in the Framebuilding Forum, that could make one for you. Andy

There are apparently stems for Cannondale bikes that have a 1.5 inch (38.1 mm steering tube interface. Not sure that helps you though.

I forgot about Crack n fail, good point. A shim could easily be made to size down. I just checked QBP's stock and they show Thompson X4/Elite in a 38.1 steerer clamp diameter. You might want to be seated before you look at the cost Andy

I have one of those here someplace. I'll see if I can find it and measure to verify.
EDIT: Found it. Without the pinch bolt, it measures just under 40mm. When I squeeze the tabs in the vise, I get 38.1. So, it could be shimmed to work.

Thanks for all the suggestions and info. I am following up on a lead -- there may be someone selling a used part. But if that doesn't pan out, I will check out these various options, shimming a Cannondale or maybe even having one fabricated using the existing post if possible as a foundation. It would be good to find someone experienced in TIG-welding aluminum. It looks as though this fracture happened because the metal had been weakened in the HAZ.

Since I work with steel I'll do the obvious wrong and blame the failure on the use of Al Andy
