Hey, here are some problems I am having with my 240, and I need to know what yall think I shall do. I got a 96 240SX SE. I know this is off topics, but id really like the help.

1) My car wont start. The battery wasnt tied down, and it seems the clap is just too loose. So im guessing i need to buy new clamps. But theres a small red box next to the clamp, and Im wondering if I can damage it.

2) My windshield is starting to crack, in 3 different places. All from little stone chips. One has lines that are about 2 inches long, the others dont have lines yet. Should i call glass auto repair guys (i dont even know the price) to come fix it, or should i forget about it and buy a new one soon(how much?), before i have to go get inspected.

3) I need new rear struts. I am not sure of cost, but should I go OEM or aftermarket. I dont care about which handles better, im concerned with price. Also, is it a job my pops and I can do, or should i get it done at the shop.

4) The throwout bearing on my clutch is very worn, i need a new one. My dad says we can do it, and replace the whole clutch while we are at it. About how much will it cost us to do it, compared to a shop. The clutch seems like way too much work for us to handle.

thanks.
