Hey guys,

Just finished my TH400 to SM465 conversion over the Christmas holiday and now I'm ready to get back to tinkering.

Eventually I want to convert my C20 to a K20, but I don't have time for the PITA its going to be with suspension, sourcing parts, T case room, etc...

So for the mean time, I want to do something about my 1 wheel drive issue I'm having with my 14 bolt rear end. :whymewhyme:
In the snow, if I keep my bed shoveled full, I can manage to get usable traction on the road, but as soon as I get on grass or an especially slick area, it's over. Not to mention driving around the farm in the spring/ summer with all the mud.
What are my options about adding a diff lock on the 14 bolt? A quick google search yielded the "Gov-Lock", which the internet didn't praise highly. Are there any other diff lock-esque things I can do to get both wheels under power? Thanks! :cheers:

Although I have not done this yet, one of my co workers swears by the Detroit locker for the 14 bolts

I run a Detroit its awesome and very streetable

sounds to me like you need to find a cucv axles set(which Im selling BTW)
they are front dana 60 4.56 gears
rear is 14bolt FF with Detroit 4.56s

the gears kinda suck but for 1500bucks you get an AWESOME axle set

That rear axle should also already have a Detroit Locker factory installed.

The Detroit Locker is the least expensive ( of his selections ) at "Tom's Differentials" @ $479.25 , and you can probably install it yourself since it goes into the stock carrier and replaces the cross shaft and spider gears.

They work great but are alittle harsh . The Detroit TrueTrac would be very smooth - but is about $180 more ( smooth as an open diff !).
