Only the flapper valves can be reused. (I just went through this on my '70 where I put a 75 1.8. (numbers 8 & 9 - if I am reading your questions correctly...)

2.0 liter stainless (pre-75) uses stainless heater pipes for the j-tube and the other one that connects to the fan.
1.7/1.8 uses different diameter tubes. Flapper boxes are the same. Muffler, muffler bracket and gaskets are different for all three systems. 2.0 liter 75/76 1.8/1.7 liter pre-75 2.0 liter pre 75 The 75/76 stuff is unique and only fits that system. All of it from what I recall, including the heater tubes... Rich |

rtowle - thanks
so the 2.0 sshe use a different elbow and jtube than the 1.7/1.8 sshe? i have some parts that are silver in pic above but they are not stainless - though i do have some stainless elbows for sale in classifieds - guess i should bump up the price of my 2.0 sshe sets and include the stainless elbows if they are needed to complete a 2.0 (only) stainless system? jim Attached image(s)

Are the j tubes a different diameter as well? I can't see how the could be as they must go up through the holes in the tin.

i managed to slid a steel and a stainless elbow onto a 1.7/1.8 sshe - my impression is that at-least the elbow is interchangeable across sshe's and regular he's ??
