Rebuilding of '61 Apache 10

[redcj576]

I have a '61 Chevy Apcahe 10 Truck and it's frame is dead.with dead I mean there are lots of cracked,and welded parts.
Later i bought a frame(With tires,both differentials,springs,coils) of '80-85 Chevy Silverado deluxe 10,but it is 40 cm longer than Apache's frame.it is a very good frame even it has the original shocks.
I have also found a frame with original engine(engine is not important because i will install V8 6.2 Diesel),i did not look at the frame but i know it is old,too.
my question is,is it better to cut the silverados healthy frame or use the old apache's frame.


thanks.

I have a 60 panel and put it on a 76 chevy 4 whl drv frame i had to shorten the frame 13 inches but i am very happy with it with the later frame parts are easy to come buy and they ride better. if you are not looking for stock i would use the late model frame
