13bt compression test SST rental?

[86trooper]

Does anybody by chance have a Toyota or aftermarket SST they would rent or sell for doing a compression test on a 13bt? (Injector hole test).
I have tried some non conventional methods with rubber gaskets and a block off plate but I’m not certain I’m getting an accurate test completed. Showing around 250lbs across all cylinders cold.

Have you got an old injector body? Could you do something like this: photos.app.goo.gl/LgWTgHyjSCboJ2ZH7

Unfortunately I do not have one. Mine just all came back with a clean bill of health. Worst case I will whip something up off the lathe and sandwich it down. Just trying to avoid that if I can!
