Chain drive diff offset

I am duilding bike engine single seat car.

The diff is a converted mX5 one to chain drive. When lined up behind the engine itís not central.

The diff type is the old one that the drive shafts bolt on.

Question is would it be ok machining a spacer to mate up the difference. Of get a longer drive shaft on one side?

If the engines central to the chassis then the front sprocket will be way off centre,like most single seaters.
Unequal driveshafts is perfectly normal assuming he diffs not too low in the chassis making the angle of the short shaft too steep!
