[Chevelle-list] driveshaft

[HarKemAsso]

HI
on my 68 chevelle, I had a 3-speed in it. I changed over to a 4-speed Saginaw trans and used all the same mounts from the 3-speed.. now the front  u-joint seems to bump a little on the floor as it goes around. Is there a different mount I should be using??

thanks for the help!!
