Now i have brake conversion kit installed, dissapointing feelings at first, seams that kit got front end wider, when trying turn steering wheel most right or left, tire scrubs inner fender. :evil :

In Summits web pages says in Q&A section that it should not do that!

Is it possible that the workshop has done something wrong while installing the conversion kit?

Could it be your tires are too wide...rim's offset not enough...front end too low?
I read that most disc brake conversion will kick the wheel out about 3/4".

Could yes, but tires hasn't change, same wheels and tires i used before conversion.
All though had to change 14" -> 15", but done that way much earlier before drove Chevy to workshop.

Never scrubbed, not even once, stance is the same, only thing has changed is tire and wheel size bigger by an inch, maybe that is the core of the problem. Sad thing, would not want to raise front end because i like the stance like it sits now...

Thinking to change front tires narrower, there is an option to get white stripe tires a bit narrower in market.

Take it to an empty parking lot then drive it in a circle. When you hear/feel the tire rubbing then stop and visually check the tire/fender.

Downsizing to a smaller diameter tire will probably also rub. Maybe a different wheel with a deeper setback (back space) may solve the rubbing.

Yes, but change tire from 215 -> 185 would make difference.
Spoke wheels are from 1974, hard to find smaller and with that kit, large disk, not possible, need to have 15" tires... :mad :

Had a similar issue with my '65 but kit info did say it moved wheels out 3/8". Just enough to make my tires rub like you mention but I already had larger wheels/tires. Got a narrower wheel and dropped tire size to clear. If you acn't find wheels with necessary backspacing/offset you can go from 215 to 185 or 195 if necessary (assuming wheels can handle it) but increase aspect ratio (i.e. from 60 series to 65 or 70) to maintain same overall diameter for looks & ride height
