I'm restoring an Excalibur machine and mostly done, but the previous owner replaced 2 bumper posts with screws. Most of the bumpers are just wood screws, but these 2 are machine screws because they also hold down the ramp metal. I'm hoping anyone with an excalibur could give me the post threading info (size, part #, or anything else that helps me replace these) so I can replace them. I've attached images highlighting which posts I'm referring to. Any help would be greatly appreciated!

Hoping someone can check this. Please .

Thanks again.
