Bellhousing Experience Quicktime vs Lakewood

I want to start a thread that will consolidate the pro’s and con’s of the different available aftermarket Big Block bellhousings specifically the Lakewood and Quicktime units. Brewer’s is wealth of information on the factory units but doesn’t have as much on the aftermarket bellhousings. There a various threads on this site and others where people seem to have problems with both. Many of them do not go into too much detail or mostly relate to header fitment.

Available bellhousings:
Lakewood 15330 (discontinued but still avail new and used)
7.5” depth, 4.807” bearing register (bore diameter)

Lakewood 15335 (appears identical to 15330 but w/larger bearing register )
7.5” depth, 5.125” bearing register (bore diameter)

Quicktime RM-6073 (more expensive and lighter than either the above)
7.4” depth, 5.125” bearing register (bore diameter)

To anyone who has installed either of these in 67’ to 69’ A-body:

Did you have to clearance the tunnel?
Which Clutch Fork did you use? Did it give trouble?
Which Fork Pivot?
Which Ballstud Bracket?
