Reply to "Pantera ZF 1"

Hum?

I do know that Ford Power Parts has an adapter bushing made to use the shorter 1-3/8" Ford big-block input shaft in a small block Ford application.
The reason it exists is that the BB "top-loader" transmission pilot snout is shorter then on the 1-1/16" small block version.
The FPP part is machined out of bronze "oilite" material.

It looks like DT had a similar transmission mismatch with the ZF in the 'goose' and decided to go the same route machining thier own adapter. Maybe the GT40's are the same way?

I don't know about the ZF you have but in the case of the Ford BB toploader and the clutch disc, the disc is not special. The spacer just extends the support to the shorter BB input shaft. By the time the flywheel is installed there is enough room for the disc hub to still find the correct zero position.

I'll bet that DT considered the cost of an adapter vs. an input shaft from ZF and went the obvious less expensive route. Most likely ZF wanted a commitment from DT to order a minimum quantity of ZF's with the correct specs? You have to cut the budget somewhere I suppose?
