3/8 dovetail on my 22 question

[hammer111]

I have a Remington 22 speedometer with 3/8 dovetail. I messed up and bought 1 piece low scope mount.

Is there a way I raise it up. I guess it would have to be dovetail to dovetail.

Or should I remove the rear sight (it's not interfering with the scope), or leave it alone. I still should be able to sight in right.
