I chopped one at the age of 16. The chop is straight forward. The vent windows and rear window are the problem areas. I worked out the issues with the vents but I was going to use lean for the rear..(have yet to finish it)
try this dude **BadLuck 52 CHOP** hes doin one now and its very very cool http://www.jalopyjournal.com/forum/showthread.php?t=627163
had a '54 Coupe with front and rear glass lowered into body. rear glass leaned forward too. no pics to share.
check Gambino Kustoms out... and BadLuck52 will get you to the same point. Same concept. Every 54 HT I know sunk the glass into the package tray, so that must tell you something...
I chopped a 54 hardtop, and used the factory rear glass. It turned out nice,I have pics if you want to see where I made my cuts. Don't use lexan. I do have a book that shows a 54 being chopped, when I find it I'll get you the tittle.
