Compression tester adapter for 4 thread heads?

[2000GTSTANG]

I bought a compression tester from Harbor Freight and the adapter is too short to thread into the 4 thread heads. What tester are you guys using that has a longer thread on the adapter?

I got one from Orilliey that works, after I already bought the one at harbor freight. They do the rental thing at Orilliey but I kept it.

Also the misspelling is Apple approved
