I'm rebuilding a 68RFE and when I opened it up it had a suncoast drum in it and the stock clutches in the re-build kit won't fit. Suncoast said they don't sell just the clutches so I need to figure out what clutches they are using, does anyone know? I figure they didn't make custom clutches and just found something bigger they could fit in there but what did they come from? Customer don't want to buy another $1800 drum that didn't fix the problem.
