Just had a look at the Strathclyde website, and the LLB (Hons) course asks for AAAAB in highers at the first sitting. I'm not sure if that means in 5th year, or just without resits.
Your best bet is to give them a call (the main campus number is 0141 552 4400) and ask. They'll be able to tell you if you will be considered, and if not they can advise on what to do next.
