LSDs - $$$$

I like having a total of 4 shifts (counting ups AND downs) at PBIR

Sort of funny. I mean, how much longer can a four speed drum braked car be competitive in ITS? Why are we racing it anyhow? It is almost 2010 and this thing was penned 40 years ago, as was I.

I don't see the problem Ron. Shifting and brakes just slow you down....

Sorry I thought the 240 could not run the late 5 speeds (oh yeah your not in a 240 duh! my bad )But seriously have you looked into that? The truck rear diffs are plentful and cheap. I heard that the OD box set likes the taller gearing and they are also a lot easier/cheaper to get. Sam N said somthing to me about that last year as an alternative to trying to fix/replace the comp boxes (and trick parts are available if you want to tweak/rebuild one).
I think this is what Don Ahrens did with his car (not IT but very close in the drive train)

Just an FYI. On the truck diffs, if you get it from a salvage yards you'll want to get the front diff from a 4x4. The rears are solid axle. Depending on the year/model of the truck the r-180's are available in 3.9, 4.11, and 4.38.

Id num for trucks is on panel in eng compartment.
ca41 r180 4.11, ca43 4.375 ca46 4.625 look for 720s 80-83
86+ hardbodies and 720s (4.11 or 4.625) also some of the frontiers had ca45 (4.54) 2003+ , started changing to r200s mid 80s so look for 4 bagers, and yes will be on 4x4 front diff only. The 4.44 can be found on some of the subies (dont know which)
I got this off the nissan-infiniti forum dont remember where old post.

Ron, I did stumble across this price on an LSD unit, but I'm not sure whether it will be correct for your ring gear diameter.
