So based off that this is a BB k-member in the pic?

I hope to have this car back together for my son next summer and it hasn't had a motor in it for 20 years.

Like I said, this is an original SB car and I remember we had a BB in it and I disticntly remember helping my dad change the k-member with the motor in. I guess things weren't lined up right and someone told him to get a kmember from a cordoba and we did.

I have no idea what motor mounts to use or what they look like.
