73-87 K Engine to Crossmember

[aotte1]

Installing a 1983 to 1987 K engine cradle/crossmember set up in a 1966 K suburban. The 1966 K frame rail is about 3/8” shorter so need to shorten the height of newer crossmember bracket.
Question on the 1973 to 1987 engine to crossmember clearance for the the oil pan, harmonic balancer-8”, and pulley serpentine belt. What is the clearance in inches. Or a close up photo of this area showing clearance between engine and crossmember. Dimension needed to determine how the bracket that fits in the frame rail is shortened. From top, engine not lowered. From bottom, engine lowered. Easier to shorten bottom, however, can do top if needed.

Thanks for information. Will post couple of photos, not mine, copied from forum.
