I am having a problem replacing the master cyl on my 80 model, the lines going into the mc are inverted, but the replacement one I bought takes bubble lines on the 2 front ports and inverted on the bottom. I ordered another one from a different parts store to see if it may be right. It is coming in on saturday. Has anyone else had this problem.

 

here is some pics to compare your part to.

All the pics I have seen do not show inside the ports. Centric brand tells you what the ports are, but are not the same as mine. The new one I got is a Fenco reman, and is wrong. The one I am getting today is a Cardone, so hopefully it will match. The part stores show a 79 and 80 as being the same part number, but some of the web sites do not, not sure whats up with that. The 81 has the right type of ports but are in the wrong position. If anyone can shine some light on this. it would be great. Thanks

 

Got the new mc today and it is the right one. If you have a 79 or 80 model you might want to avoid Fenco, Both of them that I got from them was wrong. Cardone was right.
