series 4 carrier??...
So i stumbled across a guy selling a brand new in the box RICHMOND 4:10 gears with the install kit for pretty cheap (compared to online prices).. I didnt seal the deal yet because i wanted to look up some stuff on the product.. Well on LMPERFORMANCE.com i found those 4:10 richmond gears BUT it says "You must have a series 4 Carrier or this will not fit without modification." in bold lettering.. Do i have a 4 series?? i looked on the sticky but it only talks about 2&3 series carriers.. I wasnt looking to buy rear end gears yet but for the price i attempted to do a little research..
anyways any info on this or advise is appreciated.

thats from the sticky..
so from that, 3 series is anything above 3.23s, i believe my car factory comes 3:42 so its a 3 series right? im just confused because looking it up on that website stictly for my car and clicking on the richmond brand, it pulls up that i need a 4 series.. if anyone can verify this for me that would be great
4 series is typically seen/used for larger rearends,not our little 10 bolt.
Yes, the 3.42s are 3 series.
looked at the website you referenced,they state a Richmond gearset,went to the Richmond site for the 4.10s and it shows for 3 series carrier,I believe the '4 series' statement is wrong and needs to be corrected/updated.

What year is your car ?
99 & later,which have a Torsen carrier,requires a 'modified' paddle to use 4.10s'.

The part # on the Richmond site is 690322-1.
Looks like The LM site added some 'coding' ID for their site.
98s' and earlier had Auburn 'posi' and an Auburn 3 series does not require any modification to accept the Richmond 4.10 3 series gear.
From all indication,they're good. BUT if you're gonna buy from them,I would call them and ask them to explain the 4 series designation since 4 series does not apply to GM 7.5/7.625 10 bolts.
