As you might have read my earlier postings, I am going to attempt to adapt a ridgid die head from a 535 or similar machine to a toledo 999 machine. I'm going to purchase the die head but before I do, I need to make sure that its physical dimensions can be made compatible with my machine somehow. Could someone take a photo of their die head with a tape measure going across it? I can extrapolate most dimensions from that. Believe me when I say I have searched hi and low on the internet.. I finally found something the web doesn't have!!! Thank you!
