240znz doesn't appear to be "clear on that"

To clarify my earlier post: The kick plates are the horizontal aluminum embossed plates screwed to the top of the door sill visible with the door open. Seen here: http://www.courtesyparts.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=CP&Product_Code=74590-S30 The scuff plates are steel covered with a black vinyl material and mount to the interior side of the door sill and are visible from inside the car with the door closed. Seen here: http://www.courtesyparts.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=76942-S30 It's not a matter of using one or the other, both are used on the car. They are shown on the parts CD (which I don't have here). Todd

The "skuff plates" are made of stamped steel and were originially covered with vinyl. The "sill plates" are made of stamped aluminum embossed with "DATSUN" Your car came with both and are sill available here: http://www.courtesyparts.com/secondtier_s30.html Todd

This was discussed here http://www.classiczcars.com/forums/showthread.php?t=22424 with pictures. Todd

Tomo, If you really want bling check these out :eek: http://www.stingerelectronics.com/web/prods/battery_terminals.asp and to answer your last question yes they are slightly diferent sizes. Todd

Gary, The side seals and the rear cover gasket can be done relatively easily with small hand tools. The pinion seal in the snout is a bit more difficult. You'll need a 27mm socket and breaker bar or an impact wrench to remove the nut on the pinion shaft, it's torqued to 120-140 ft lbs. Once you get the nut off you may have to use a puller to remove the companion flange. I put the diff on my bench with the companion flange in a vise and used a breaker bar to break the nut loose. The old seals pry out of their locations fairly easily with a screwdriver. The new seals are tapped in with a hammer. I used the old seals placed over the new seals when tapping them in to protect them from the hammer. I bought new seals and the cover gasket from the dealer. FYI, McKenna is about 20 miles south of Tacoma and about 20 miles NW of Olympia. Todd

In addition to the cover gasket there are several leak sources on the differential. There are oils seals on each side where the halfshafts enter the housing. There are rubber o-rings on the side bearing retainers that could leak.There is an oil seal at the front of the housing (pinion seal) behind the drive shaft companion flange. The drain and fill plugs could leak if they aren't tight enough. Oil can leak out the vent at the top if its installed wrong or if the diff is overfilled. You can't change the cover gasket without pulling the differential since the cover bolts directly to the mustache bar. Todd
