Count me as the odd man out here...... they SUCK!
Their carb bogged off the line, a problem they claimed to have fixed. The chock coil was in backwards. Plus a couple of other problmes. Called them about 10 times to fix the problem. All they told me was my dizzy was junk, the balancer had moved, my vac gauge was incorrect, blah-blah-blah.... bascially that everything ELSE was wrong but their carb. Asked them for specific settings like Accel pump. They said that there was no "measurement", only that it worked when you pushed in the gas. Funny.... but the FoMoCo manual has a measurement spec. So I rebuilt my DOPZ replacement carb and all my drivability problems went away.
Bottom line, if you by something "mail order", you are stuck with it. Pony does NOT stand behind their product. Yous pays yer money and yous takes yer chances.
