I'm not sure where you got that idea. The 2016+ Access Cab variants all have a 6' bed and can have a 5 or 6 speed manual depending on the year. You can go on to Toyota's website and spec an TRD Sport with a 6' bed and 6 speed manual right now.
For sale is my 1986 Toyota HJ60. It has the 2H diesel, 5 speed manual transmission, and of course 4x4. It’s registered in Washington State and located in Goldendale, WA. I imported it from Canada myself, and have since spent a ton of money on it. If I keep it, I’m going to keep spending tons...
Looks promising and a great price! I'd go and buy this one if it were on the other side of the continent and I hadn't already traveled to Canada in November to buy an HJ60!
Can you estimate the mileage on the engine? Perhaps do a compression check?
