435 conversion - intermediate housing seals

[DanWheeler]

I'm installing a 435. I can't seem to find either of the intermediate housing oil seals (front/back) on NAPA's site. They won't list a pickup with a 4 speed manual.

Does anyone know the part numbers? I was able to cleanly pull the front seal from my stock intermediate housing only to find out it's slightly too small for the 435 intermediate housing. Weird. Not sure about the rear but I'm pretty sure I won't be able to pull it without trashing it anyway.

I bought the 435 w/ adapter and intermediate housing. It didn't have either of the seals. Is there any good reason to go without them? I do want to install the seals, right?

thanks,
dan

really? let the transmission fluid mix with the transfer case fluid and fill the intermediate shaft?

I'm talking about round shaft seals here - not gaskets.

I used the same fluid (Royal Purple) for both so I don't think that it would matter anyways.

There is no round seals in there the last time I took it apart...
Plus you're using the same gear oil in both of the gear boxes. Right?.

not too sure on the fluid - it's been a while. Probably the same.

I guess what I'm more worried about is getting on an incline and transferring a large amount of fluid from tranny to t-case or visa versa and leaving one dry.

The only seal between my 435/dana 20 combo is the one in the stub shaft/bearing retainer at the t-case, if that's the one then try a skf 13557, that's what mine took(I dug the box out of the junk).
