BT7 Rear Suspension

So I have started reassembly of the car. Take a look at the pic. Rear axle in the car, rear springs mounted, fibre plate on top of spring rebound rubber on top of axle. The square plate that the U bolts go through has a hole in the centre that the pin holding the spring stack together goes through.

It wonā€™t fit through the hole as the nuts are to large to fit through. So do I remove the nuts, install plate with flat washer, and secure the plate to the spring or ? (Sorry, the pic is sideways.)

Please clarify. The plate holes are too small to allow the U-bolts and pin to pass through? To install, compress the leaf spring with C-Clamp or bottle jack, the offer up the plate to U-Bolts and nuts and tighten evenly until the pin eventually passes through center hole. Good luck.
 
Correction. Mount the plate, then use C-Clamp or bottle jack to compress spring until U-bolts can pass through. Then spin on lock washers and bolts and tighten. What is it? 40ftlbs of torque?
 
Thinking about this some more .
The springs I have for this car are new , they came from Marty at Jule (yes I got them years ago) as he recommended them to use with his superstructure.
They have to use BJ8 bushings at the clevis hanger end of the spring . The BJ8s have bigger holes in the spring base plate .
So my choices are get BJ8 spring base plates or just drill the existing plate slightly larger to allow them to fit over the spring stack pin .
That seems to be the way to go for me .
thoughts anyone ?

No the hole in the centre is too small for the spring stack pin .
see additional post above .
 
I think that is my path right now , once I get my parts from AutoFarm which include a lowering kit for the front and rear suspension I will look at it further but It shouldnā€™t change the plate below the spring as itā€™s a spacer that fits between the spring and axle and longer U bolts .
 
Don't lower the front too much or you will high-center on dead squirrels. I originally used the DWM lowering kit and had to raise the front a bit to get out of the driveway. You will also need to install guards for the anti-sway bar mounts.
 
The kits lower the car 1ā€ front and rear , Tks for the tips .
 
I've been looking for a rear lowering kit and the AutoFarm tip is appreciated; however, in reality the 1 in drop would not allow the car to clear the driveway. I may just order a set to experiment with.

Time to regrade the driveway šŸ˜šŸ‘
 
I ended up using some 7/16" (IIRC) nuts between the lower A-arms and spring pans to lower my front end. That results in about a 3/8" lowering of the front. I didn't lower the rear.

Thatā€™s basically what the lowering kit for the front is , manufactured spacers to place between the A arms and spring pan together with longer fasteners and also a spacer disc to put between the rebound rubber and spring pan to maintain its height relative to the bump stop .

The DWR manufactured spacers are about 3/4" high, so the overall lowering was ~1" to 1-1/4". I just took pity on my oil pan.
