First time doing ladder bars and have them mocked up and have the ride height i want but looks like i'll only have about 11 inches from upper mount to lower mount. Does that sound right? or do i need to cut through the rear floor and bring the upper bar to a higher location? I havn't bought the shocks yet and not sure which ones will work. 68 dart 3200 lb car with me What would a typical lenght coil over be? What spring rate should i start with?

In general terms you want the longest shock you can get to allow for movement. Ladder bars will need a fair amount of extension so if it were me I woudl look to move some stuff to get a longer shock in there.

The first coil over ladder bar car I drove had a set of 3 inch travel AVO shocks, 7 inches extended center to center, not good That car would fully extend those shocks on the starting line when foot stalling it against the converter at or above 3500 RPM My current ladder bar car has a set of Strange double adjustables that are 16.5 inches fully extended center to center,9.0 inches compressed center to center, lots of travel My upper mount is in the trunk above the stock trunk floor PM me if you want me to post a picture of it, not trick but it has worked very well 1.39 60 ft so far foot braking, not great but not bad either

what type of shock are you wanting to use? stock mount? aftermarket adjustable's? may want to concider a adjustable lower mount.

It;s an adjustable but i havn't welded them on yet, still trying to figure out what length shock to use but looks like i;m going to cut out some of the trunk to raise the upper shock support to achieve at least 13 plus inch height.

S&W sell a long shock mount that you use adjustable brackets on... weld it on then get the longest shock that will fit... make when you weld the brackets on to give enough room for the pinion to be rolled up or down for pinion angle... this is what the bracket looks like.... once you get it figured out you can cut the bottom off

Better to lower the bottom then raise the top. I had 14" qa1s on my 69 Dart. they bottomed out on our bumpy return road all the time. I switched to 17" and couldn't be happier.

Ok, Got the shock mount brackets in place, Shocks mounted and need to figure out how high i'm going to put the upper shock support. Reading the shock install instructions they want to have the lower adjuster at approximatly 1/3rd up the shock and they require 60% of the travel to be for compression. So far seems to be lookin ok. See anything that needs redoing?

How thick are your ladder bar brackets... they look to be about 1/8" max... I would go heavier... 3/16" and weld a gusset to the axle housing down to right near the lower bolt hole to stiffen that otherwise it can crack... here is a pic of my 9"... this pic is before I welded on the gusset(I forgot it till I got done painting... and I had the gusset laying there on my welding table... but I wanted to paint it)

The gusset I'm talking about doesnt come with any kit... if you look at my last pic you can see where the lateral link hooks on at the right... that black triangle thing slightly above is what I'm talking about... get a piece of 3/16" stock and make one (the bottom of the ladder bars where the lateral link hooks on takes alot of side loading going around corners)... also I weld a piece of tubing on the bottom to attach to the shock brackets(part on the rearend) to help stiffen those(bottom bar in pic)

Ok now i'm confused. Got the shocks mocked up and followed the instructions and even going past half way on the adjuster it will not begin to suspend the car. Shocks are DS 501 QA1 single adjustable and the springs are 12" and 130 lb all as recommended. I'm nervous about adjusting them too tight. If i were to try to put them in different holes i'd have to find a way to compress them. Any advice?

Lets start over. You appear to have the S&W kit, just like mine. You'll see guste tubes at a 45 degree angle to the mounts like Mike suggested. Make a pair of tubes to take the place of your shocks (see pic). Make them the correct length for your shocks at mid point travel. Set the lower brackets at mid point and see where the upper end lands. Too high? Move the brackets at the bottom into the lower holes. Attach your upper mount. This part is done. Now screw the platforms up on the shocks 1" and lock them. Mount the shocks on the car . Adjust the ride height with the lower mounts. Doug

Got the ride height i want, now it's very hard to take off the wheels & tires. Looks like the easiest way will to unbolt the lower shocks to let the axle hang down to remove the wheels & tires. Any of you guys use a pin on the lower shock instead of a bolt?

I would not use a pin. Heck it's not even legal to pin a seat back to the cage. If out ever fell out it would be disaster. I let my tire come down an 1" or so and tilt the bottom inward. Doug
