Floridastang 13 Report post Posted June 20, 2018 Finally getting the 69 on the road and have a vibration that I believe is frame contact somewhere. It is an automatic car with a floor shifter. I see evidence of rub between the shifter housing and the transmission. The car was an FMX car converted to C6. I installed the proper mount but am not sure if it installed correctly. The right side , passenger, straddles the crossmember the left side only attaches to one side of the crossmember. The left side has two bolt holes I have it attached to the upper hole but I’m thinking if the lower one will work perhaps it will solve my clearance issue. Thanks for your thoughts on advance Quote Share this post Link to post Share on other sites
