Should be no bother, but take the table off, might be an idea to put it in first.
I'd get some thick short bits of fenceposts around 3" thick to get clearance for hands, plenty of old jackets
or carpet or even cardboard for protecting paint of the machine whilst sliding, and car more importantly, and then some more for packing in.
Not knowing if you can/plan to take seat out, very easy to remove with only one little bolt at the front on some older cars, (but beware of grease which is kinda difficult for someone like me who has only done so once for annual mot, possibly some more carpet would do here.
then an easy job.
Also remembering I forgot to pull out plastic grease covers of tracks and cracked one, doh )
or disassemble base if possible.
Might be an idea to have some of those posts fixable/slotable/stackable/how ever you do it,
to take the brunt of the weight of the fulcrum,
if you're planning on tilting the column (spine) side down and sliding in from the top wheel first
and then tilting the heavy lower half in after,
as the plastic lip/ or whatever you call it, and boot lock won't get damaged,
Motor side will likely be a lot heavier since these have seemingly sheet metal wheels,
although there may be something solid in them too.
Good luck with it.
