Control Arms Mounting specifications.
 

i want to change my original S10 control Arms with Blazer control Arms, and i need the mounting specifications for them (angles, bracket distance, etc) major issue is that i need to build a new motor mount/ front crossmember . the S 10 has Spiral suspension and blazer has torsion Arms. as im giong to add air ride suspension i dont mind to cut/modify blazer control Arms for that, but first i need to know how to properly mount them. here is picture of the Control Arms that i have.

Off the top of my head, you might be better off just getting a 4wd S10 P/U or 4wd Blazer that would have the torsion bar suspension in the front. It was only the 2wd versions of both that had the coil springs in the front.

They also used different wheels with different offsets.

thanks , but it seems i have not explained my request very well. i Already have all the front suspension from a Blazer, the one that shows in the graphic. (Left and right, upper and lower arms, brakes, calipers, stabilizer bar, etc. ) i want to fit that suspension, in a s10 year 79 , i need information on how to mount it ( perhaps the best informacion will be a Blazer chasis blueprint that shows the mounting Angle for the Arms, distance beetween them, etc) im pretty shure i will need to build a new front crossmember / motor mount crossmemeber. i have all the tooling (metal cuttin laser, cnc metal bender, cnc machinig center, etc..so fabrication is not a problem for me.)
thanks.
