I have 3 of these, got them for the GT40 project (now abandoned)
Did have 4, but used one on the MK, fits nicely and very powerful.
Got them new about 8yrs ago, so could call them new old stock.
I paid about £120 each for them, so I think £60+pp each would be reasonable.
Still available as VA10-AP70/LL-25A LINKY
Build up stand
Very useful, with 4” pivoting castors, 2 of them locking. Good in a small garage, can push the car from one side to the other.
Fully adjustable for level, could be used for a chassis jig base.
£50+pp
