1968 Eldorado - Master Cylinder Help!

[PerryB]

Looking for any assistance locating the proper brake master cylinder for my '68 Eldorado.  Shop has ordered and received three incorrect units so far....not sure where the complexity is?  The numbers I see on the cylinder are 1380L near the top, and just below left is 6122A.   My parts book says it's a Bendix model part number 1494859. 

The brake lines enter on the passenger side (right) of the installed cylinder (one sent was backward).  The piston has a hole in the center about 1 5/8" inches deep, where the brake pedal pushrod goes.   Also, the inner diameter of the piston "sleeve" is about 1.020 inches (Others have had incorrect bore depth and/or piston diameter).   

Don't want to cut the rod, or otherwise modify to make something work....how do I find this master cylinder?

Pictures attached.

Any leads or education here appreciated - Perry

I would recommend you send the master cyl. AND booster to a good rebuilder & get them done. HTH, Bob

Anyone in particular that can be recommended?

Karp's brakes is my recommendation. I have heard from several people that they do very good work.  I believe this is the website:   http://www.resleeve.com/index.htm

Hope this helps.

I had same problem. The easiest is to buy a power brake booster for a 69 or 70 eldo and buy a new master for the same.
