Does anyone know the correct torque of the lower motor mount bolts for a mid 70's shovel? I can't find anything in the manual. I know 35 ftlbs is standard for the 3/8 fine thread.

According to My OEM HD Service Manual for 1970 to Early 1978 FL/FX Models it states to tighten Mounting Bolts to 35-40, ft-lbs. Torque.
This is on Page 3-8, approx. 2/3 of the way down on the Right Column of the Page, if You may have the same Manual.

Just as a little more additional information...according to My OEM HD Service Manual for 1978 1/2 to 1984 FL/FX Models...
It states to tighten the Mounting Bolts to 33-38, ft-lbs. Torque.
Tighten the Rear Bolts first, then the Front's.
That is on Page V3-11, under the Installing the Engine Header.

That's the way I've always done it. Rear first. Then I check for a gap at the front with feeler gauges. I will shim the front with Chevy starter shims.
