1946 Distributor

Hey guys

46 auto lite distributor 1at-4011

I always have a time getting roll pin out of shaft

File then guess at pin location and hit with punch one size smaller than pin

To show location I've tried dykem blue, dye penetrant, and heat

Usually by dumb luck I finally hit it

No luck today

Any advice

Also need vacuum advance

Thanks
