Have a powerglide trans for a 69 camaro that the 4 bolts are missing. This has the plastic shield and the metal / rubber shield that goes on the drivers side( to protect shifting linkage I guess). It mounts with the 2 bolts that hold the plastic cover on the drivers side. Ricks has 2 sizes for these sems bolts 1/4 or 5/16 can anyone tell me the correct size for this instalation?

1/4 inch
