/6 to magnum mount options

Pretty sure all Magnum blocks have LA lugs or ears still on them. Never seen one without them.
Very early blocks, like 92 and 93 model years, are the ones that have LA lugs but lack the later Magnum truck bosses.

Got a bunch of snow here but I will still try to get pictures this weekend.
Like I said, the early Magnums do have the truck mounts- they were being used to mount 5.2s into 2wd Dakotas, '92-'93. Both styles were used from the beginning, have never seen a Magnum without provisions for both.

Magnums in '92 were 5.2 only, 5.9 came in '93. The 360 roller LA was still in use in '92 when the 5.2 Magnum debuted.
