If your gonna practise welding start to make a jig for your car there is a website out there for escorts etc etc - shouldnt be too hard to convert it to a Granny - although it does weigh a bit more - You can pick up engine stands for fook all - but as long as you have the dimensions from your engine then welding one up should be a doddle and with yourself doing it you can make your own custom one should you feel the need. Wish I had space to do summat like that
