Just changed my mini starter . 440 auto TTI long tube. Didn't have to pull the arm off the box, just dropped steering linkage completly. I unbolted the header from Engine and collector after taking out all spark plugs .Had to move around the header but didn't remove. Just barely got starter out and in. Didn't touch the torsion bar. I know 440 has a higher deck so maybe you can unbolt the DS motor mount at K frame and jack motor up enough to get more clearance for moving the header out of the way. All said took me 3-4 hours and patience. Still happy it can be done.
