I'm in need of a bunch of nuts, bolts, washers, and hardware to put together the rest of the 455. I can source most of these bolts locally from a fastener shop or the local hardware store. But I need to know the exact sizes of each first (ie. thread, length, diameter, washer or not, etc). Does anyone know where I can find a good reference to get all the correct bolt sizes for the motor? Below is just a partial list of the hardware I'll need:

- Trans to Bellhousing Bolts
- Bellhousing to Motor Bolts
- Dust Cover Bolts
- Flywheel Bolts
- Starter Bolts
- Clutch Pressure Plate Bolts
- Trans Xmember to trans Bolts
- Motor Mount Bolts
- Carb to Motor Bolts
- Fuel Pump Bolts
- Starter Bolts
etc., etc., etc...the list goes on.

Thanks for the replies.

I've wrestled though identifying a few bolts as I worked on my '68. It is sometimes tedious. The Pontiac Parts Catalog often (but not always) shows fasteners in the Illustrations Sections. (I use the 1972 version that I got from Bishko) Sometimes you then have to dig into the part groups in the catalog's Parts Sections to obtain the application, finish, hardness, or other details.

I believe an on-line version of 1st gen applicable pages may still be available on line somewhere.

Thanks for the reply Jim. I'll try and ID some of the bolts through the catalog.

If anyone else knows what the actual bolt sizes of anything above, please reply. Thanks.
