70rivme Posted August 23, 2018 Share Posted August 23, 2018 I am currently replacing the motor mounts in my '70 Riv and see that each side is different. I had already ordered new mounts from Cars and just unboxed them. They are both the exact same mount. Before i try to install these and run into an issue, has anyone else come across this or have any expertise in the motor mount field? My engine has a larger and a smaller mount installed while the ones i received were both the larger type.Thank you all! Link to comment Share on other sites More sharing options...

Buick Farm has the correct LH (driver side) mount for 68 Riv 430 but they don't carry the correct RH mount for 68 Riv 430. The driver side mm is probably the more critical mount to replace as it takes a majority of the stress of engine block rotation. (The block lifts on the driver side). My original LH mm sheered in half and luckily BF had the correct replacement mount. BF has a 69-70 Wildcat RH motor mount for sale on their site: https://www.buickfarm.com/29/101/gm-group-0-clutch-engine/p-motor-mount-rh-with-weld-nut-1234598. Not sure it his help you or not. Finding correct mm's is tough. Good luck. 1 Link to comment Share on other sites More sharing options...

Thanks for your input and direction, I greatly appreciate it! I ordered the left side mount from Buick Farm late last night as that is really the one I needed, just like you had described. I would like to know how people are making these other mounts work that appear to be close, but are different. 1 Link to comment Share on other sites More sharing options...
RoadShark Posted August 25, 2018 Share Posted August 25, 2018 At the bottom of this thread you can see what I did. I used the cheap NAPA mounts. They were close, and workable, but definitely not like original. https://www.v8buick.com/index.php?threads/1967-riviera-motor-mounts.326776/#post-2735663 Some people send out for revulcanization of their originals, but it's pricey. 2 Link to comment Share on other sites More sharing options...
PWB Posted August 25, 2018 Share Posted August 25, 2018 (edited) CARS cant even get motor mounts right amongst all the sub par items sold to me. Im done with them. I’ve wasted enough time and money.

It cost me $119 for just one mount. Edited August 29, 2018 by NC68Riviera (see edit history) Link to comment Share on other sites More sharing options...
