Sorry I don't have pics tonight. I have a 60 Chev lwb and mine has a 350 and a muncie 4-speed. My front engine mount is actually a horseshoe shape that bolts to the front of the block with 4 bolts and then one bolt at the bottom. On the rear it has mounts on the side of the bellhousing. There is no side motormounts like on a latermodel.
if you are pulling out a 230-250 6-cly motor you can use your old frame mounts, and use the rubber mount that are bolted to them, just take the mount apart and bolt the rubber mount to your block, if it is a 292 6-cly you will need the passenger side frame mount. Very easy install. email me if you still need pictures.
You should also consider the cooling system. If you are replacing a 292 then you can use your old radiator. It is the same size as V8 equipped trucks. You will also need a fan shroud or aftermarket electric fan(s) due to the fact the V8 sits farther back than a 6. The 230-250 equipped trucks used a smaller radiator and may not provide sufficient cooling.
If you are planning on air conditioning then get a heavy duty 4 core or "Desert Cooler" If not then a standard 292/V8 radiator should work well. Brothers truck parts has a good selection or you could look for a used one. Of course with a new one , you know what you're getting.
