In my conversion, I need to add 1.8" to the spacer for the Saab clutch cylinder (as shown).
The easy way is to machine another "donut" spacer that is 3.5" OD and 2.6" thick. Easy being a relative term, as the raw material will be a nice chunk of change, and there would be a good chunk of time in the machining. It would also be heavy.
An easier way would be to use the current .8" thick donut and use three 1.8" long x .5"OD standoffs to space the donut to my desired distance using longer bolts. I can buy 2" long aluminum standoffs from McMaster Carr and shorten in a few minutes, making it a $10/10 min job.
So my question is ...... is there radial loads involved that make my idea problematic? The 1/2" OD standoffs are the appropriate diameter for the width of the machined surfaces on each end, but I could make 3/4" OD work too, or I could make the standoffs out of 1/2" x 1" square material.
For reference, the bolts are M6 x 1.0 and 100mm length will work for either option.
I would appreciate input. Thanks!
