As usual most helpful guys.
The clearance issue in the garage (plan A) may work, as I think I can position the bonnet area under the duct and the boot area under the garage door. After all, I just have to get it off, roll the chassis out from underneath, and lower the body onto some sort of dolly affair to roll onto the trailer. As advised, I will get out the tape measure and go from there.
Something similar to Sean’s solution is my plan B. Luckily ran into a friend today (Vic) who is into Brit bike & car restoration. He not only has a trailer available to haul the removed body to the body shop, but has some scaffold frames that should work if we have insufficient clearance in the garage. Most particularly appreciate the balance point advice!
I have checked the side rails and confirmed they have been replaced by PO and are in good shape. Am planning the 1/2" bolt and wood side frame/cradle idea as primary hoisting method. Have confirmed 1/2" bolt fits jacking points well.
Planning photo’s of the event for sure. I mean really, how often do you build a whole car!
Getting really excited about this whole deal. Sure the better half will come around when she sees the progress! 
Getting parts order finalized, shipping costs outlined now from Andy, and just finalizing a few items.
Have drawn up a realistic schedule as per advice in Gord Lund’s book.
Looks like a busy winter! Schedule shows LOTS of work prior to arrival of parts from Spyder, which is great. Have left time for other commitments, Christmas etc. so I actually think this is doable.
Have tentatively booked window with the body dude, which will get body off site for quite a while. Vic has trailer to assist with hauling.
Lining up storage for other car and motorcycle to make sure I have workspace for the project. Have a couple of options, will finalize shortly.
Thinking as per Gord’s book to rent close by temp storage for parts such as seats, etc. that are not needed until next spring. Space is tight, and this seems a worthwhile way to go.
Have sorted out engine repairs and diff check-out (water pump mainly, preventative check on dif) with local mechanic Malcolm (lots of Lotus experience).
Malcolm sufficiently enthused with project he said he will help with body re-install & chassis tapping; has done several “back in the day” when apprenticing.
Received advice from Vic to “go for it” with soda blasting of body. Have found a guy locally that rents the space, equipment, booth, safety gear and all materials/cleanup on a hourly rate. Vic has done this before with bike frames, etc. using same guy’s equipment.
Got hub removal tool and wiring tools on order from RD.
Anyway, sorry for length, but thanks again for the great advice. I am certain I am going to need a bit of help/encouragement over this winter, but really looking forward. As usual, if you think of some thing I have missed let me know.
