Your description isn't exactly clear. There are 3 different bolts that pertain to the particular motor mount you mentioned: 1) two that bolt the mount roll stopper to the cross member; 2) one that connects the roll stopper bracket to the roll stopper; 3) two which bolt the roll stopper bracket to the (in case of a 2G) transmission.

1) M10 x 1.25mm pitch x 30mm long
2) M10 x 1.25mm pitch x 75mm long
3) M12 x 1.25mm pitch x either 28mm or 30mm long.

From the dead. The bolt that goes through the center of the mount on a 1g is what size exactly? I appreciate it.

There are two different bolts listed for that particular mount on a 1G, either should work as they only differ in length.

M10 x 1.25mm pitch x 75mm long or 80mm long.

Thank you Sir. I will get the longer one. Rather be safe than sorry.

Bringing this up from the dead because I just found my rear mount bolt stuck between the cross-member and firewall.

For the rear mount itself, there are actually 3 bolts mounting it on the cross-member.

Would like to confirm that there are only 2 bolts mounting the mount bracket to the transmission itself. Because it looks like is the possibility of 3 bolt holes places... would just like to confirm one is not missing in my case.

I will definitely have to replace the bolts which runs through the mount itself as it is striped.

To be clear, the information given in post #2 is for the front mount.

Correct.

There are three bolts connecting the rear bracket to the transmission; they are all the same size.

Any know the size of the bolts that hold the mount bracket on the transmission for the rear mount? I was trying to remove one yesterday to find out, but it's really stuck on there... soak with PB blaster so we'll see. I definitely need to find a replacement for the missing tranny bracket bolt though!

M12 x 1.25 x 28, the same as the two for the front bracket to the transmission.
