For those of you (Joey specifically) who were wondering about the sizes of the engine bolts on the 350 for purposes of replacing the 'green' bolts with stainless, here goes:
Body M8x1.25x20/30
Strut Bar M8x1.25x20
Radiator Reservoir M6x1.0x20
Engine Cover M6x1.0x12
Earth Ground Plenum M6x1.0x12
Headlight M6x1.0x20
Factory Airbox M6x1.0x30
Struts M8x1.25 Hexnuts
Plenum M6x1.0x12
Hood Sensor M6x1.0x12
Power Steering
Reservoir M6x1.0x30
All would need SS washers
The kit from 'boltdepot.com' includes the following sizes (plus add'l bolts, splitwashers, flatwashers)
M6x1.0x12 30
M6x1.0x20 20
M6x1.0x30 15
M8x1.25x20 15
M8x1.25x30 10
Again, this kit has ALL you would need to replace all but the oddball size in the 350 engine compartment. Price in the $48 range for the entire kit. A bargain.
Hope this helps anyone intereszted.
I'm assuming that the other versions of the Z (240,280,300) all use some of these same sizes in their engine bays.
