Hey Guys, Bear with me here, Ive searched and answered some of my questions but still have alot of unanswered ones. The main one being besides the transmisson on 95+ 240s are there any other differences between the autos and manuals? (rear end, driveshafts,etc.) And why in the world did nissan make the lower models 4 bolt while the LEs got 5 bolt hubs?! Lastly, Ive been checking online for 97+ front end parts and the headlights come in around 400+ US! Does anyone have a better source? I have had a terrible time locating stock fenders aswell. Ive found plenty +20mm fenders but none that are stock. Is the 20mm addition up front really that significant? I really dont want a front end that looks wider than the rear. Thanks in advance! ---

I have a front bumper for sale, the headlight is pretty much sold (bumper is damaged tho). [http://www.son240sx.ca/forum/viewtopic.php?t=9865&highlight=fs+97+bumper](http://www.son240sx.ca/forum/viewtopic.php?t=9865&highlight=fs+97+bumper) for more Kouki front end parts, look up a guy named Jason, he goes by S14\_240sx. He can get Kouki parts cheaper than I have ever seen, but buy my front bumper, kay? TheoK ---

I don’t know this for a fact but common differences auto/manual ECU - you can usually run a manual car on an auto tranny ECU, but not the other way around. Auto ECUs often don’t have a rev limiter. Stuff like neutral saftey switch, lock up etc. can be ignored. Driveshaft - aut tranny ones are usually shorter, as auto trannies are usually longer. Diff ratio - being short a gear (4spd auto to 5 spd manual) auto gear ratios are usually numerically lower. I don’t know about the S14 for sure, but if you check the firewall tag (the metal VIN tag in the engine bay) there will be a category that says TRANS/AXLE- there will be a code there that says RC41 or something similar. I’m not 100% sure, but the R is the R200 rear diff, C is the transmission designation (FS5W71C) and the 41 is the diff ratio (4.10:1). If you have an auto trans car, look for the RC?? number, and you’ll be able to tell if your diff is diff.
