Hello again,
I guess you can separate it in few ways, but I decided to have frame on wheels on the ground and lift off the body. I used two jacks (one motorcycle platform jack and one 3TON car jack with jacking beam). I jacked it on both sides simultaneously. Once I reached limit of jack height, I used jack stands on each body corner to put body down. Once on stands I put some timber on top of jacks to be able to raise body higher. I had to repeat this operation few times to get to point when I could roll out chassis backwards to my garage and leave body outside. However before that I had to remove jacks and stands from body corners as they were in the way. To do that I slided 2.4m timber over axis so they would stick out on sides and lowered the body on stands again.
Few issues I found :
1) make sure to find balance on the beginning when jacking body up using 2 jacks (they were platform/beam ones so they support body on distance of over 0.5-1m each side). Otherwise it will be really dangerous!! I would not try it with 2 normal car jacks for sure. Make sure you do it on hard surface.
2) you need to raise body up by approx 0.5m
3) remove your shifter stick as it will be highest point on chassis and you will have to raise body even higher then 0.5m.
4) do it really slowly as you might forgot about disconnecting something
5) don't do it alone
Yesterday night I also removed engine with transmission. Bad news is that the gearbox has a hole (picture below). Basically nut went through casing... I drained oil (what was left), but it is maybe 0.3-0.5 L. I know the reason now that the car was out of commission from 1990... It is not engine that was dead, but gearbox... but now engine is also trashed due to coolant corrosion. Can't win...
I will open gearbox this weekend to check if it can be saved (it turns on every gear ok). I stay positive that I need only new cover, but I'm also prepared mentally that bearings are gone and I need total rebuild or new gearbox. Time will show. Bearings are quite expensive when looking on Delorean websites, but I will get UN1 service manual (bearings sizes) and check prices at bearing shop. Maybe I will get lucky...
Plan now:
1. Gearbox - split and decision what next with it
2. L7X engine out of Laguna
3. Adapter for UN1 gearbox
4. Fabrication of new engine mounts once L7X connected with UN1 and dry fit to frame
5. Frame - once modified with new engine mount brackets -> sandblasting and galvanizing.
6. Reassemble of frame (brakes, fuel system, suspension etc - all overhauled or upgraded in meantime).
7. Powertrain fitment.
8. Body back on chassis.
9. Wiring
10. New interior
