post # = how many holes on the mount.

Just go on the site of your choice to buy mounts and you just choose car and motor and whamo, new mounts on the way

well does it matter what motor it is (b18a, b18b, b16, b18c, etc) because i heard that the mounts are different. or is it based on the chassis?

Just order them for a B-Series into a 92 civic.

92-94 Civics have the 2 post. 95, All Civics came with the standard 3 post mounts. I know on Ex's anyways.

Some 94s have the 3-Post mount.

So it doesnt matter. Integra and Civic moutns are the same.

are you referring to the driverside mount bracket that mounts against the block?

are you talking about the studs that stick up out of them? because you want the ones that came off a dc2. because the patter looks like this:
___O <----- stud
O <-----hole for bolt
___O <---- stud directly aligned with top one

EK cup style 2 post mount bracket studs look like this:
O

__O

they are not aligned over or above each other..
2 post doesn't work the same to my understanding.. hope that helps brandon.

BUT Gerry.

Civics our body style also came in 2-bolt mounts.

I think hes refering to stock 92-95 Civc mounts and 94-01 Integra mounts.

yeah i checked mine out to see and i have a 3 post mount. yeah i was referring to the driver side. thanks for the visual there gerald. but yeah jarrod i do have a b series so i believe i need the dc2 mounts. cause i found out you can use a 2 post for a 92-95 civic but only for b16. i guess b18's are different. but thanks again guys for helpin me out. ima go ahead and order some hasports soon.
