"exact fit" Tesla Model 3-Y adapter for Safejacks Rennstand Better than original

Description

These are "pinch weld"adapters for the Safejacks Rennstand.  They are sold for 5 each only by Safejacks Rennstand. No Rennstand is included with this adapter.
Sold each;  adapter allows the Safejacks Rennstand  to closely fit the jacking socket on the chassis Model 3 or Y.
This composite close fitting adapter is much better than the loose fitting steel tube stub welded to a steel plate and a tubular post.  The locating bushing is machined for a close fit out of blue acetal Delrin.  The center is counterbored and through bolted with a 1/4 inch 18-8 204 stainless steel disk threaded to a tapped aluminum center post.
The stainless steel disk closely matches the support ring of the jacking point and not beyond.  This effectively prevents any likelihood fof damaging the battery liner
The jacking block fits securely into the top of the Rennstand.  The added benefit is that the adapter can be mounted onto an aftermarket manual or electric scissors jack.  Tesla supplies no jack and one is not available from Tesla.  Any flat top scissors jack with a flat top or a riveted on swivel can be drilled with a 1/2 inch hole to secure the adapter to prevent the car slipping off the jack and damage to the expensive battery.
Additionally, it can be mounted on a hockey puck (not supplied) or a block of wood by just drilling out a 1/2 inch hole.  This allows direct jacking with any standard floor jack.
No assembly is necessary.  The jacking adapter is fully assembled and ready to use.
This sale is one custom made adapter block (sold each) marked in photos with a red box. No vehicle jacking sockets or Rennstand shown as a mounted example are included.
