E28 rails in E34?

[BigD]

Can anyone tell me if the E28 seat rails would fit an E34 (ie is the bolt pattern the same)? I'm putting in Sparco seats into the M5 and I'm thinking of putting the M5 seats in the E28 and using the E28 manual rails for the Sparcos. Or should I just find used E34 rails?

Thank's!
