Easy, the insurance card reads 65/66 and that is all that is required in Houston or as far as I know, all of Texas. Cost $12.50 for safety only. Had mine inspected several years in a row at different places and not once have I had any problem. Inspection stations do not need to see any title or anything else, only proof of insurance.
Hope this helps. Texas is a pretty easy state to get replicas titled/inspected. I can tell you they have stopped titleing them as 65/66. If you need proof, go downtown Houston to the main DMV and they have pictures of Cobras on the wall with warning signs to employees about titleing them.
