Lowering arms or drop spindles?

I'm using Chevy C10 front suspension parts to rebuild my '37 Buick Roadmaster.
DJM offers lowering control arms for $737 and drop spindles for $310.
http://www.djmsuspension.com/applica...s/C10Parts.htm
The control arms have improved geometry for, but I should be able to make some of these improvements when we design the mount brackets for the arms.
1) If I only only want 3" drop, am I better off with the new lowering control arms or the drop spindles?
2) Can anyone share the pros & cons of each approach?
Thanks

iirc the arms are to keep the engine crossmember and arm mounts(at crossmember) above the scrub line. if use'n tall tires or big rims(17"+) it's not much an issue with spindles..
if you are making the arm mounts, you don't need either. you can run 3" drop springs, and fix the alinement issues that come with them ,because you are fabing the mounting points

Thanks for your help.
I do not have any of the front suspension parts yet, just want to buy parts one time with no regrets.
My current plan is to run 16" wheels with either 235/50 R16 or 225/55 R16 tires. This will drop the car a couple of inches.
I want this car to handle well, but still be a pretty comfortable driver.
1) Based on these tires, would control arms, drop spindles, or drop springs be the best choice?
2) I'm using the original Buick spring pockets and I believe they are not as high as the stock truck, so drop springs may be required just to prevent lift. If drop springs do not help with drop, will the drop arms or drop spindles be a better choice?
Thanks

I'd get the stock spindle andarms and mock it up and see.. the c-10 whole set up bolts in/out of the truck. why not just slice and dice it in.. and use it's spring pocket..

I am still considering using the complete C10 cross member because it mey be less fab time, but I have a couple of reservations on this approach:
a) I think the cross member will add lift to my car because the Buick frame will have to be bolted/welded to the top of the cross member.
b) By designing a custom upper bracket I can move the upper spindle back and add caster that I do not thing the truck cross member will have.
Using a stock C10 cross member would probably be less risk and make the fabrication.
1) Do you think the ease of installing the stock cross member and reduced risk would out-weigh the disadvantages?
Thanks
