don't know, but if you jack up the front of the engine out of the supports , so lowering the gearbox , the top bolts will be more visible ?
not all trannys have a separate bellhousing …. ?
if so , for the 2 top bolts you "need" this…. don't know if 17 or 19...
Here is how to solve your problem in 40 seconds:
Pull tranny by removing 4 nuts
Now you can see the 7 bolts on the bell housing
