Need this inside part. The spindle is attached and holes are 1 3/4

Hello there!

Thanks for reaching out to us. Start by taking a look at the 40-150. This inside handle measures 1-3/4" on the installation hole centers. It's designed to accept 3/16" spindles but if you remove the insert in the handle, it can accommodate a 5/16" spindle. Review the specifications and see what you think.
