I use the factory bolts that connected the engine to the transmission, I did have to cut the engine stand mount tubes down to 1" for them to work... but it was midnite and you do what you to do... I have since used it this way several times with no problems....
IF you have never done this before (replace the engine in a 100 series) you might want to read some of my posts from several of my engine swaps...
a few notes:
I pull the engine with the a/c compressor and just recharge the system after... saves a ton of time and is just far easier in my opinon.
a 15mm ratchet wrench for the bolts at the top of the bell housing is nice to have
The hard lines to the transmission have a mounting point under around the pass side motor mount that are a Beach to get to
pull the engine with the exhaust manifolds and with the complete wire harness disconnected from behind the glovebox and pulled through the fire wall...
only disconnect the the fuel line from the fuel filter (time to replace filter anyway)
IF you are using an engine from a non 100 series... you need to use your oil pan, oil filter mount, exhaust manifolds, and motor mounts... and maybe throttle body (depends)
everything else is plug and play...
