i can't see paying $1,500 to Decah for a simple door conversion....and they call it a vertical door conversion....not even vertical....started making my own kit but i was inching towards $900 and stopped b/c you'd have to do frame work...so i'm doing a bolt on design which i should be done with shortly and it will be vertical doors that go up 70 degrees...just like in those pictures...
"VDC Vertical Door Conversion Kit Manufactured By Decah
The first TRUE vertical door conversion complete bolt on kit. No welding or cutting required. EVERYTHING is included to do the conversion. The kit includes:"
it's not even vertical

i'll probably sell it for $200-$300 for everything....but i'll have to spend some hours testing it at the junk yard....but i will finish it and have it installed on my car
