upper pan removal

[xvr420x]

15. Remove four oil pan-to-transmission bolts.
16. Remove two engine-to-transmission bolts and install them into
open bolt holes shown. Tighten the two bolts to release aluminum
oil pan from cylinder block.




i got this out of the 2000 silvia FSM. I have a redtop and the two bolts that they say to use to get the upper pan off are too small to thread into the holes shown. Do you guys know if it is different from an s13 to an s15. or do you know of any other bolts i might use to get that sucker off. The engine is in the car so im having a hard time getting that upper pan off.
