69 Need Help!!

[Mel Foye]

Brand new here and need some help. My driving error and got T-boned by a late model Sub in the left front tire.
LF frame got moved pretty good.
Mine is a base 69 C 10 Suburban, 2WD, 406, auto, power disc brakes from a 1 ton and 8 lug front end. Also friend found and added PS as a x mas gift. Towed 5,000 of race car up 4,xxx grades in 100 degrees and went from 180 to 185 degrees. Back up to wife's Vette as these are the only two automatics we have.
It is important to me in that we have had it since 7-1-77 and this feels close to losing a pet.
What are my frame choices? From what I have read here 67 and 68 won't clear the PS. Have spotted a local 72 Sub frame. Will that bolt on? I have a 72 1 ton 8 lug 3:70 leaf spring rear end that I was going to put in anyways. Do the rubber bushing control arms ride better than the steel to steel in the 69s?
I am glad I stumbled on this place and I know I have not paid any "dues yet" by helping others but really could use some advise. Thanks Mel
