Need verification/validation on these GM part numbers

[badmix]

Im getting ready to order some seals for my Blazer from GMpartsDirect and their response is less than stellar. THey are very slow with emails and dont have any direct phone numbers. ANyways, I asked about what part numbers I need and they sent me a diagram and then some part numbers. I just want to see if anyone here can verify them.

358589 passenger's removable top lower weather-strip.​

357490 removable top on cab weather-strip.
15590455 removable to, on top weather-strip.
326934 end gate weather-strip.

Its an 1984 K5. I want to replace the seal around the tailgate, and want to take the topper off and replace the 2 bedside rail seals and then the topper to cab and then the cab seals.

When I called the dealership a while ago they told me that #13590455 is the seal I need and GMparts says its #15590455. so, just want to make sure I order the correct ones.

ALso how do these seals go on? Ive never had my topper off. While I need any sealant or do they press in like the door seals?

Thanks

You need sealant. I can't recall what I used, but I may be able to find the tube.

As to the part number, it's either a misprint or the part number changed, which does happen.

I can check my parts manual at home and see if the '85-88 one says different.

I'd trust this:
