I'm starting my winter projects a little early, and want to rebuild the calipers. I'm staying stock, and want to do the fronts first.
What part numbers should I be looking for? It seems like there are a few variations out there, and frankly, I don't know what I'm going to get when I place an order.
Here's what I found so far:
A/C Delco # 173-511
A/C Delco # 18H170
A/C Delco # 18H86
It looks like 173-511 has been replaced by 18H170, but Limey/White Racing (http://www.whiteracingproducts.com/index.php?main_page=index&cPath=6) lists both. From what I can tell on his website, part/kit 173-511 contains two piston seals, two boots, a bleeder screw cap, and a c-clip, where as 18H170 contains just two seals and two boots.
The A/C Delco site (http://webcaps.ecomm.gm.com/internet/VehiclePartDescription.jsp?selectedfld=&application=Car%2FLight+Duty+Truck&year=1991&make=CHEVROLET&model=CORVETTE+ZR-1&engine=V8+5.7L+350cid+GAS+FI+N+Engine+VIN+%3D+J+++ +++&productline=14&part=1720) shows 18H86 containing only one seal and one boot. The problem though is the pictures of 18H170 and 18H86 on the A/CD site show what appear to be different seals and boots.
Here's the next problem. Since I want to add speed bleeders, it doesn't seem like I wolud need the bleeder screw cap. But where do I find a part number for the c-clip? NAPA wasn't much help, and I can't find anything online. :mad:
Can someone point me in the right direction?
