I would be surprised if there was a CFI out there who wouldn't sign off for you. Even time in the T-34C from way back in your career should suffice I would think, let alone time you have in other HP/Complex aircraft since then. I actually need to do the same thing, and I was just planning on dropping into the FBO here in town and seeing if anyone would sign me off. I'll get back to you on whether or not that is kosher.
I'd appreciate it. All my HP/Complex time is T-34C as well, though I've been eyeballing the Arrow down at the flying club. It's just a bit of investment to fly it solo.
