For a second look at your frontend alternative-

I don't think the angle on the bulkhead will cause any issues.
We should have given you a heads-up on the bulkhead, I had to double up the thickness on the A-arm bolt hole supports- These tear out pretty easy with aggressive driving.
I use 12" shocks and it performs great, turning the A-arm upside down looks like it might work.I haven't done the Heim set-up yet as the HD ball joints from BD are still going strong, but when you do the bungs for the Heim your shock bracket may interfere.
Definitely drill the grease zerk in the A-arms so you can lube them without removal.
Also adding gussets at the top of the frame where the bulhead bolts up keeps the welds from failing over time from constant beating.
This probably should be moved to 150 tech. What would you like the title to say and I'll move it.
