There are a couple of options available if you are willing/want to retain the original bellhousing/crossmember mount.
The stock 60-62 V8 installation with a standard transmission has a U shaped motor mounting bracket with a single rubber mount similar to the 235. If you can find the bracket and mount it's a simple bolt in. I've never looked so I don't know how plentiful these are. It's shown on page 8-59 of the 1960 Chevrolet Truck Shop Manual. The downside with this arrangement is if you want power steering. A conventional p/s pump may not fit since it appears the U bracket would be in the way.
1960-62 trucks with an automatic transmission (very rare) had multipiece box style motor mount towers that bolted to the front crossmember and used conventional style side motor mount pads. I found one set in a wrecking yard 20 years ago that I couldn't get (the engine was still sitting on them). I've seen a few sets on EBay but they are rare and very expensive. I'm not sure if the rubber mounts are available, or if these towers (rather bulky) would interfere with a p/s pump. The automatic equipped trucks also came with a bolt in transmission crossmember that uses a conventional tail mounting pad. Should you ever consider installing an automatic transmission, you must convert to side engine mounts and use a trans tail mount crossmember. Every 60-62 frame I've seen has the mounting holes for this crossmember. There are 3 per side in a crescent pattern so it's easy to know where it bolts on. 20 years ago I went through over 50 trucks to find the one I have, and I have seen only one other offered on EBay, so they appear to be even harder to find than the motor mount towers (although the crossmember would be somewhat simple to replicate). Going this route also requires cutting out the standard shift bellhousing crossmember which is welded in place.
On my 1960 GMC I used 1967-72(?) motor mount towers with stock 67 style rubber mounts. The frames are different between 60-62 and 63 up. The height of the frame rails where the towers bolt on are shorter on the 60-62. I simply placed a solid steel spacer plate between the tower and the frame, then attached with grade 8 bolts. It's been years but I seem to remember the spacers being 1" tall. To arrive at the correct alignment I bolted the engine to the trans/rear mount, attached the motor mounts and towers to the engine, then lowered the assembly into the chassis to identify where the holes needed to be drilled on the crossmember and frame. This later style tower is readily available on EBay, and I believe there are also reproductions.
Side motor mounts along with the original bellhousing trans mount should result in an incredibly strong setup. The beauty of retaining the bellhousing mount is that the transmission can be pulled in minutes by simply removing the driveshaft, and the tin clutch cover under the bellhousing allows easy access for clutch replacement.
Classic Performance offers tubular engine towers, but they are 63-72 only. I called quite a while ago and asked if/when they were going to release a 60-62 version and was told it was not under consideration.
Hope this helps.
