Kinda like lowering blocks but built into the spring perch. Smith Racecraft 3131 Winnequah Dallas, TX 75212 Phone: 214-330-0660 Fax: 214-466-1877 I'm Gumby dammit!

I used a reversed eye in the leaf for about 0.75". I used the -2.0" leafs, and I went to adjustable rear leaf hangers and used the upper hole....

Mi.	i use 2" lowering blocks on mine, some will say lowering blocks have a negative effect on the suspension geometry, i dont agree. i've been 1.27 60 ft on et street radials, no wheelie bars with sigle adjustable Rancho truck shocks. i say use lowering blocks.

I got the idea from Overkill racecars on YB and had lem made to my specs. Mine look like these, I don't have a pic here at work. Steve Photobucket sucks

Looks like it's pretty close to the outer wheel well as it is, and I'm guessing with just a mini-tub the tire can't go inward any further?... Here is my Mini-tub duster pics, Not much room to stuff a 13.5" in there unless it's right on the frame rail. 5576846-IMG_1796.JPG (177 downloads)

We are using the stock ride height Calvert split Monoleafs on our Valiant, and our car is not anywhere near as raked as your duster. The springs were brand new in this pic, also. 29.2" tire in the back, 27" in the front. 5576979-Mark\'s68Valiant.jpg (159 downloads)
