I am installing 3-point retractor belts in my 70 targa. Like a dog that won't give the stick back...the retractor part works great, on both belts. I cannot seem to get the release, to well...release. Am I going to have to disassemble these things? And if so...which side cover should I go after? I've had issues with finicky retractors before...but after a bit of tugging they released. Your guidance is welcome...in fact requested nicely.
