69 cuda 340 slipper clutch?

I kind of find it strange that quick time and Lakewood do not custom modify and certify bellhousings to fit your order.or do they ? They must be aware that alot of there product has to be modified for soft loc clutches. I'm sure some ppl would pay to have it done especially if they are throwing huge power through it. I think Tim Hyatt will certify a modified bellhousing if you want or need them done . I'm yet to find out that a modified bellhousing for an adjustable clutch doesn't pass tech at any drag strips.
