Personally I would prefer a skyhook but lacking one of those I've removed and reinstalled the rear clip of my SPF MK1 by my self but it requires mechanical help. The first time I put the rear clip on by myself I used a moving pad and a two wheel dolly. Not a process I would recommend or ever do again.
With a little preparation an engine hoist works very well. I used some lifting straps from Harbor Freight threaded through the carburetor cold air intakes. It balances very well and is a straight lift to remove it from the car (don't forget to unplug the tail light wiring). If you have the room just leave it on the hoist with some padding, if you don't transfer it to a hook hung from the ceiling otherwise you have to deal with banging it into the legs of the hoist when you put it down and pick it back up. You can ask me how I know but then I would have to lie.
Mutt, you can R&R the front clip by yourself but it would be a piece of cake with two people, I lay out a moving pad in front of the car, remove the nostril, unhook the wiring, undo the two latches and wiggle it off, the rear part of the clip with the latches just make it over the top of the tires. You may have to pull out slightly in the area of the rear latches so they can be lifted past the chassis parts in that area. Just remember to go slow and easy. It's much easer with the front tires off but then you have to put the front of the car on blocks which is kind of a hassle. At some point it will slid off the car and on to the pad. Its a little heavy for one person to move around but it's doable.
I started a project some time ago like Alan's that will use a barn door rail system but like many other projects it's currently on hold because the car is now registered and the weather is just too nice. In fact it's time for a little road trip right now.
I found my build to be very rewarding, a few of use have done their own and know how hard it is at times. If you need information or just encouragement we're here, just don't ask for money because after my build I'm ready for the poor farm, but after you drive it the first time you'll know why you did it. Best of luck.
