I have a 2000 civic SI and I need the lower motor mount the one on the transmission side I know someone parting out a GSR and wanted to know if I can use the mount off of that car? Also are these mounts really necessary cause I just bought the car and it didn't come with ether of the lower mounts but I got the one for the AC compressor side

 

Part #50843-S04-N10 is the bracket that bolts to the transmission. Fits the following based off of honda/acuras interchange 96-01 integras (manual transmission), 99-00 Civic Si, 96-97 Del Sol (not sure on sub model, but I would assume its the one with the b16a3). Some people say they are needed, others say they aren't. If you have softer/stock mounts I would keep them. I have 75a hasport mounts and I still have both of mine (with energy suspension inserts), some people with really stiff mounts remove them and call it a day.

The actual rubber mount itself should be the same for the passengers side for the cars I listed above, I would have to check on the drivers side.

 

oh ok I also have hasport mounts so do u think I should buy the mount or just leave it without that side
