Looking for some hardware to run SunOS 3.5 and 4.1.1

I'd like some sparc 3 (not 3x) hardware to run SunOS 3.5 and 4.1.1.

I want/need 2-3 seperate working machines in the end, tape drives
and such would be nice, monitors and keyboards not needed.

I'll basically take anything and am willing to part together from sun
manufactured parts.

I'd like to locate these in the next week or so and have them on hand in
1-3 weeks.

Any assistance you can offer would be great.

Thanks very much.
