Anyway to make a Road Crankset fit an MTB Frame?

Hey guys,

i hope this hasnt been asked already. Im building a bike at the moment, its an titanium frame that once was an mtb. now i found solutions for most problems but the newest issue is the crankset hitting the chainstay even without being fully inserted. its a shimano bbr60 bb and a shimano 105 (50/34) crank. is there some spacer trickery so i can use the double road crank and dont have to switch to 1x?

Thx in advance, can provide measurements and more info if necessary.
