So, I suppose there’s a rule here.
This is a picture of my car chassis, 5ft up in the air to put the new pedal-box at a sensible welding height. I’ve never had it this high, but it makes a difference.
What you see are a pair of hydraulic pallet-lifters bought from ebay for under £100 each. They’re stable as buggery (or rum, sodomy and the lash) and each is rated to 350KG. Bearing in mind the fully laden car with me in it tips the scales at under 700kg, all is groovy.
Normally, I have one of the scissor lifts much nearer the front but without the engine in, it balances quite nicely where it is.
