no 5=how many holes/bolts and 130mm or 112mm relates to the the distance between bolts. if you use the 5x130 on the 5x112 the holes will not match up because the holes are more spread out than the 5x112.
It is used for lining up bolt holes on flanges. You hammer it in through the bolt holes and it lines the holes up. (Hopefully)
6 lug holes
No, the spacing between the bolt holes is often different.
some birds, sometimes bees, and squirrels, sometimes field mice
once you have removed the hub nut you will need a flat metal plate and a nut & bolt. The plate needs to have 3 holes in it, 1 in the centre and the other 2 to line up with the wheel bolt holes. use 2 wheel bolts to secure the plate to the drum, with the nut & bolt through the centre hole. use the nut & bolt to put tension on the hub shaft then tap the bolt to pull the drum off.
Bolt holes were used in the trenchs to hide away from and bombs coming, the bolt hole werent so very big so it was a very cramped space.
Plumbers tape. its a metal strip with holes in to put a small nut&bolt through
Are you asking which ones to use on the block itself? What year of block do you have. Pontiac has basically 3 styles. The first is a two bolt design up to '68. The second is a 5 bolt design..from '69-'75. Then a 3 bolt design from '76 to '79. I'm going to assume you have a 5 bolt design. You will need the engine mount brackets from a '69 and up Firebird with a Pontiac V-8. It will use 3 of the bolt holes in the block. The upper hole and two of the lower holes. Buy the correct rubber mounts to install on the frame and you are good to go. Hope that helps.
It will not fit without an adapter. The 5 in that number refers to the quantity of bolt holes. The 139.7 refers to the distance between adjacent bolt holes in the pattern. In other words the distance between the upper most bolt hole and the lowest bolt hole in the pattern. Obviously, if the distance between the bolt holes is off by 25.7mm, this wheel will not fit. The only option is to purchase a bolt pattern adapter commonly referred to as wheel adapters, to change the bolt pattern of your vehicle.
YES they will bolt right on it with no problems. If this engine is to be used on the street, it would be advisable to add the steam holes to the heads. You can use the gasket as a template to mark where the holes go.
can be, starter bolt holes,bellhousing holes.
