What Transmission?/ Shifter question?

[Tug86]

Picked up a used transmission and I am not sure which one it is. Looks like a W56, it a a top shift but what is throwing me off is the shifter does not pop out like others (G52 or W56). It looks like you have too remove four bolts and plate. Will work on getting picture posted but it might be awhile. The boot is square. Thanks
