when is it time to rebuild my 87 13b? it has 222,000 original miles and seems to be running fine! but as a first time owner im not real sure what to look for. and where can i find replacement tail light covers at?

 

1) read the FAQ
2) 2nd gen sale section, you can post a WTB (want to buy) thread, or just search the for sale threads

 

If nothing is wrong then it doesnt need a rebuild.
If you plan on porting, replacing or upgrading engine components, or there is a serious problem then thats when it should be done.

 

Don't fix it if it isn't broken.
