Tubular 20b/FD subframe
Here are some pics of the hand built subframe. You may also be able to see the dry sump oil pump on the drivers side.
Had the Pettit subframe, used it to make a jig, threw it away, threw the jig away and started from scratch. Not even the slightest bit pleased with the Pettit subframe

Sorry my reply is so late guy's...
The Pettit subframe I have including spindles is for sale. The only thing I didn't like was how the steering rack mounted. They used 1" square stock that pitched the drivers side of the rack higher than the other. Supposedly the spindles corrected the bump steer. I talked to pettit's engineer and they have changed thier design.
-the oil pan wasn't an issue with or without a dry sump. we built a new oil pan for the dry sump anyway...
if anyone is interested make me an offer for the whole package forced240@hotmail.com
