Oil Pan Bolts

Dropped the oil pan out of my Buick last night. Getting dark & I was over cars for the day. About to reinstall it & notice 2 bolts are longer than the others.

Where on the pan do they go? Engine is a Buick 350 in a '69 Skylark.

Thanks for all help- I need it ATM.

Just as a random guess, they are all on the same plane, with no spacers. The only real reason for two to be longer appear to be the two that go into the aluminum timing cover. This could be so that they can all have enough thread strength to take the torque value. I would lube them a bit an put them in the timeing cover.

Makes sense to me. Thanks Bob. I'll be glad when this is over. Front disc conversion, offset upper shafts, tall upper ball joints & an oil pan with rust pin holes in it.
Slowlly grinding my way through it.
