[DeTomaso] Brake question

[Rob Dumoulin]

Certainly.

Below is the link to Summit Racing for the SSBC A0730PL. I got the Chrome
one not the black shown.

Here is a pic of my front trunk as shown on the cardomain site I setup
years ago and haven't updated for a while. I really need to take some
updated pics!  One thing I noticed when redoing the brakes was that the
windshield washer bottle fits nicely tucked under the hood latch. The stock
water squirt hose brackets easily hook up to the firewall and release
bracket and the hose length is perfect for that position.
