Steve, Our striker kit includes a double threaded insert that increases striker retention substantially over both the original and conventional "nutserts". To answer your question the thread is 5mm. Rob Grady -----Original Message----- From: Steve Stankiewicz [mailto:protodelorean@xxxxxxxxx] Subject: [DML] Need help with thread size of Lower Engine Cover Striker Hey everybody. I need some help determining a thread size. On my car, the lower engine cover striker (part no. 100597) was completely missing, including the threaded insert in the engine cover itself. I'm ordering a new striker, but at the same time I need to get a threaded insert to match.
