[Vwdiesel] Engine

[Herold, Walter L]

I recently bought an 89'Jetta, in surprisingly excellent condition.  The downside is that it has 372k miles on it.  So, before it fails, I'd like to get started on a replacement for it.  Where would be a good place to look for a long block, either freshly rebuilt, or in need of one.  Also, will the 1.9 fit/ bolt in to replace the 1.6?
Thanks
Walt
