70 gmc drum to disc

[piratedog]

(70 gmc) hey everyone, only my 4th time posting for info, i scanned the posts for a while but was unable to see a clear answer for a swap i want to do.i want to swap my manual drum front brakes to manual disc( i like the feel of a manual brake) i have a complete front end for a 71 with disc including crossmember and rear axles, can i bolt this crossmember right in to my truck complete using my dual reservoir master and proportioning valve (if im keeping manual brakes) and will the axles swap right in ????

thanks in advance!!!!
