TTI headers which ones to use?

I have put two sets of the 1 7/8 headers on A bodies.....one had the number 7 slip tube and was a small challenge on the driver side....the second set went on yesterday and because the car did not have torsion bars tti suggested the E body version which has no 7 tube welds...Big Pain in ***,,,,had to drill no 7 bolt holes to next larger size....otherwise they would go on....even took them off and try to put them on an another engine on a engine stand....

Had problems getting around the steering column...since the column was gutted I took it out to make it easier...
