after mesuring last night i found i had to revamp my trans mount on my cross member to replace the t350 with my t400 i took the mount to work and cut and ground and changed it around and brought it home and reinstalled and luckly it fit. now my mock engine is mountd with my new soon to be rebuilt trans. it is amazing the size difference between the to trannys. anyway i just wanted to tell a group of guys that aprecate progress and old trucks. thanks for reading my rambling
