forgot to mention/note...the original coils i belive put the measurements at 33"frt. and 34"in back (according to my lmc catalog...which is only good for this type of info./diagrams)so maybe that might give more tire clearance....

Buxman,
I have a 4/6" drop on my 1969 LWB, and I am running 255-60-15's on the front and 275-60-15 on the rear. I have run this combination for several years with no contact problems.
Good luck, J

BUXMAN66 you should be just fine as long as you have a 3 1/2"-4" backspaceing on wheels. We run 255-60-15" on rims with these backspacings and do not have a problem on any of our trucks dropped 3" in front and 4" in rear.
