swapping in a van frontend

[Porkchop]

I posted this in the 67-72 message board because I thought I would get more responses, but I guess I will try it here now. I found a complete front crossmember off of a chevy van and am wondering if parts of it will bolt to my 69. I don't what year van it is off of. The junkyard owner said that it would work under my truck if I just used the lower control arms and brake parts, but not the actual crossmember. He gave me a price of 150. So, do you think that this would work for my truck? I have a 69 3/4 ton. I am trying to put in 5 lug disc brakes and want to lower the front end a little with lowering spindals. Does it sound like a good price?
Thanks for any info
