New to the C10 forums(s). Seems to be no shortage of interest in the 67-72 C10 with 3-4 forums on the Internet.

My son has recently acquired a clean straight 1967 C10 long bed (and purchased a used/running LS engine and trans for it. A local guy who is very experienced with C10's has chopped the frame and bed to convert to short bed. As expected, I've spent a couple of hours searching the 3 major C10 forums and learned a lot, but would like some suggestions in the area of suspension drop, ride height, wheel and tire sizes and parts and or kits that get the job done on a modest beginner budget (read: not the cheapest way to go, not the BEST/MOST expensive).

Basics: He does NOT want the LOWEST drop possible. He wants to actually use the truck occasionally to haul basic stuff. Seems what I've read tells me the stock rear is 2" higher than front and most popular drops are front/rear drops of 2/4", 3/5" and 4/6" to achieve "level" truck". He seems to be aiming at the 3/5" drop based on recommendations by guy doing some of the work. Plans are to go with 5 lug on all 4 and disc brakes (at least up front). Interest in wheel diameters between 17" and 20" (old school dad prefers 17-18, but has 20" on new 2016 Silverado levelled with 1.75" front rise using Bilstein adjustable to level)

All this said, what are some suggestions of HOW to do this? 2/4" drop vs 3/5" drop pros/cons? Parts and work required for either? What (max) wheel and tire size combos work to fill wheel wells for both 2/4" and 3/5" drops without rubbing issues?

I've read very BUDGET ways to do things and EXPENSIVE (BEST?) ways to do all this. I don't think airbags are in the budget at this time, BUT if able to acquire good USED (craigslist and eBay are great), maybe.

BTW, I've found the following suppliers with seemingly top notch ($$$) products

http://www.classicperform.com/

Summary
2/4" vs 3/5" drop parts required
Max Wheel/Tire sizes for either 2/4 and 3/5 drop
Disc brake recommendations
Steering component change recommendations
LS engine/trans mount recommendations

Thanks in advance for your recommendations based on experiences

1. 2/4 vs 3/5 is same drop spindle in the front with either stock spring or one inch or more shorter spring. Rear is several different ways either a 2 inch block between axle and trailing arm or two inch shorter spring in the rear. Note; when buying 5 inch drop rear springs your`re at the bottom very close too frame, will not carry much more than a simple tool box about 200 lbs without hitting frame, then you get into C-notching the frame to gain clearance. My suggestion is no more than four inch drop rear with using the Heavy duty four inch drop springs for the rear( that is what I have ) purchased thru CPP.
2. Disc brakes two different styles to consider, standard as found on all current `73 to `87 chevy C10`s and burbs, they move the wheel centerline out 3/4 of an inch per side, not a problem if your running stock or near stock wheel/tire width, not sure how much of an issue that is on a 67 to 72 series truck though. Second option is the modular disc brakes, the only move the wheel centerline out 1/8 of an inch.
Going with wide tires you`ll need the powering steering from any `73 to `87 C10 or burb. To make the engine install easier go with the Dirty Dingo LS C10 slider engine mounts, makes life much easier, you`ll also need to change trans mount I believe and if your going to run air you`ll need to change the compressor mount ( its low on the right side frame interference).
I`m with you on the old school, no more than 18 inch wheels, so you`re or his wheels is what will drive this build....with issues or not..! Here is a pic of mine with the 3/4 drop, although a `64..with 275/60/15 on GM six lug rallies.

This might not only be my .02 but CPP & LMC wouldn't even be my Last Choice! Both Companies have Bad to Very Bad raps. Early Classics now Mark & Stan are very nice to work with and will Stand Behind any thing they sell. Here is two places I have found that work very well for me, 1 is ClassicMuscle.com (Modern Chevrolet) 800-334-0165 or 336-722-4191 ask for there "Restoration Dept" 2nd is PerformanceOnline.com (POL) 714-278-0098. I have/use 5 67-72 C10 Forum Sites that work well for me, this one being one of them. Ask questions on other forum sites about how they feel about your choices (CPP, LMC) you might be very surprised in what you learn. All above is just my .02.
