[project 911]

Hi All-

I'm thinking of updating my 70 2.2 to the newer style chain wheel supports. From what I've seen, I'm looking for the 80.5 and up versions. I found some advertised as follows:

These are from an early 80's 3.0L engine but the part numbers on the gears are the same 84 Carrera 3.2L which was the same for 3.3L Turbo's as well.

My question - Is there an easy way to tell visually if these are the wider ones? Do they have a bronze bushing or anything?

Also, can these be used with my original 2.2 tensioners (rebuilt + collars), or do you have to have the 930 tensioners?

Pressure fed versions aren't in the budget just yet.

Thanks for any advice.
