Question for the board... I have an early 68 aluminum case that will be run with the early IS shaft with straight cut gears. The early shaft rides directly on the Al case and is located to a shimmed steel plate by the thrust from the stock helical gears.

Since there is no thrust generated from the straight cut gears, I was thinking of inserting a spring of the correct length and OD (so its not slopping around) into the splined tube that mates the IS and oil pump to provide that force so that the stock shimmed plate can be used for location.

I have seen somewhere on this board where the splined tube has had a pin inserted as well. The spring would not need drilling or welding and provide the missing thrust pressure.

Any thoughts on this would be greatly appreciated!
