Threaded reverse lockout is 101 or 105. What diameter is the trans mount? Odds are it's a 105, 1964-1967.
I didn't understand that. Sounded like: "the whachamacallit is connected to the hoozits". Do you push the shift knob down to engage reverse? Or does it have a solid shifter and a mechanism to stop you from going directly from 5th to reverse?The reverse lockout has a boss and a bolt in the shift tower.
"Spider" just means convertible. Better to say "the input shaft won't fit into a bellhousing from a <certain year> or <certain displacement> Alfa". And how doesn't it fit? Too large, too small, ???It seems to me that its not from a spyder,as the input shaft will not fit the spyder bell housing.
Ah, got it! So it's a "push the shift knob down to engage reverse" type of transmission. Since it's a 5-speed, it could be from a Giulia 101 or a 105.The mechanical clutch trans has a small threaded stud and locknut to adjust the reverse protection. It's threaded into the shift tower, adjustable for the pin that's actuated on the shifter stub when you push down the shifter. Hydraulic clutch trans from late 67/68 on don't have it.
