Very similar on the TC-399.

The motor pulley is the same base number 3-518-067, there are 7 fine speed variants of this for 50Hz and another 7 different part number variants for 60Hz.

On the 399 the pulley sits on top of a Table Ass'y, motor pulley holding X-3472-029-0 but I cannot easily see this part in the 377 manual.

The 399 manual says to test speed using a test tape and then fit appropriate motor pulley to get correct playback frequency ! cannot see this test in the 377 manual.

The idler (assuming it is Idler B, driving) has same number 3-472-152-0 but there is a slight difference in Idler Tire part number 3-472-155-0 for the 399 and 3-472-155-01 for the 377.
