V...I used the robart 632 set up. Its a 90 degree retract with a 4" offset 1/2" diameter strut with a 4" wheel. The demensions from robart allowed variably minimal retrofitting into the wings. The length demention to go into the wheel well was right on as well. If i could go back, i would consider going with the #153. its a larger setup and accepts up to a 6" wheel. Would have looked a little better, but the 632 are bout 150 bucks on the cheaper side!!! They still look alright tho.
