May wish to consider rubber or pneumatic isolation mounts. If the glass windshield can't float it will stress and....... The door latches could need consistant reallignment as well.
Could not see photos, maybe my software is inadequate. Anyway I have a welder as well with lower skills. Therfore I paid the $4,000+. Not sorry I did, surprised by the weight though, mine is 900+ lbs or in other terms, about $5 a pound. Good luck.
