13B sumps ?

[MikeLMR]

does anyone know what the large round section on the 2nd gen pickups is for ? my old 12a pickup just has a small flange. Whereas this 13b has a massive round flange with the same shaped gasket as the older pickups and some odd looking drillings and bits in the oversized flange section :confused:

it looks like this ...

To put my 13B TII into the 12A chassis I simply bought a GSL-SE pan at the local dealer! It took some explaining to get him order the part I wanted (along with providing the part # myself) but it was very easy that way. I used the 12A oil pick puck tube, as the TII tube is wrong for the GSL-SE pan. Easy enough: everything can be used either way. The holes in the "old" (pre-86) 13B engine and those in the new (FC, FD, cosmo, ...) are all the same, you can bolt onl to new and vice versa. Preparing the engine for the transplant was extremely straightforward. I had the 12A engine out and 13B in the car, in less then a day.
And yes, the GSL-SE oilpan uses a rather shallow oil bowl, much like a 12A pan, in fact.
