Stovens; It's just like Shoprat said, I just went out in my shop and looked at mine.
I was expecting the one end to have long slot in it for adjustment like the old dodge 727 torqflight did.
But it just has a hole at either end of it, mine seams to be made of a copper type tube.
And it is only as big around as my little finger, If some one tells me how to post a photo
I'll bring it in and snap some photo's of it. Kurt
