Through bridge replacement bridge... Should I?

You're sort of correct in your assessment. It's basically just a piece of stamped and bent sheet metal but perfectly serviceable. Since you mentioned the fact that you prefer the vintage 3 saddle style, I like the stuff that Marc Rutters makes http://ruttersguitars.com/home.html and it's hard to find any better. Armadillo Guitar does some vintage style stuff in brass that's way cool as well http://www.armadilloguitar.com/shop...th=2_3&zenid=283a0bd045848473d49900579aab1d87 . There's Callaham that you can check out along with Hipshot and KGC. You can explore the inexpensive route from the discount houses such as this http://www.guitarfetish.com/3-Brass-Saddle-Tele-Bridge-Chrome--IN-STOCK_p_30.html or StewMac and Allparts. Angelas has reasonably priced genuine Fender parts and so does Warmoth if you prefer. Well...you get the idea. Lots of possibilities. Hope this helps...

 

Most of the suppliers that I mentioned are very helpful and easily approachable by email. Simply tell them that you're looking to replace the top loader on your '87 E-Series MIJ tele with a 3 saddle type of higher quality and what would they recommend that will fit?

Your English is fine. It's my first language and I still can't get it right.

 

the key here is the 3 screw fitting on yours.... (at the back) ....

. many Squier/Mex/replacement Tele bridges are a 4 screw fitting.... not too many have the extra holes on the front edge corners, either....

are US standards 3 holes still?...

something to be aware of on your search...

 

I have a late '90s (~'98) "Crafted in Indonesia" Squier Tele that came with a bridge like the one you pictured, it had the through holes in the same relative location. If you install a shorter, vintage-spec bridge plate, it's the original 6 string through holes on the body, not the bridge mounting holes, that will be exposed. Below is a picture of that conversion on my Tele.
