lwb laying frame ?`s

[2002yanks]

i got a 67 lwb fleetside and plan on laying frame. i have been gathering parts over the winter and now its getting close to install time. have a few questions and could use some help. i have searched and searched but couldnt find what i need.

waiting to install i have a sectioned crossmember(2"), pb narrowed a arms, slosh tubz pb hood hinges, unisteer u joints and bar for steering, pb front extreme shock mounts and shocks. kp bolt in monster notch and watts link, custom rear bag plates for outside the frame behind the axle kyb shocks, and ridetech air ride control, ss7 and 9000 bags. also a set of 7" front and 8" rear rally wheels. will be running 27" tall rear tires and 26.5" tall fronts.

what i have been looking for is potential clearance problems with stock trailing arms on the frame. i do have 1" drop blocks now(so it helps some). also i have a 250 i6 with 3 ott. i have a one piece driveshaft with cpp trailing arm crossmember. couldnt find any pics of 1 piece driveshaft( on lwb frame laying out). any issues there? or do i need to switch to a two piece driveshaft? if anyone has these pics or any info post away. if you had issues and solved post up what you did . thanks!
