The Revains website says 1.5 is what I want for my 03 GMC Envoy need but I really need a 2.0 adapter. I removed a few threads in my block to make it on ((((((((((((((((((((((()))))) from me from from from from from from from from from from from from) making sure you have the correct threads)))))))) on your adapter.I ended up getting a 2.0 from Summit races in Georgia and used lots of Permatex thread sealant and when powering up the motor fingers crossed (installed an aftermarket oil pressure switch and gauge). I think Amazon has 2.0s that have larger male threads than 1.5s.
