1966-81 Chevy H/J Series

[junkmandan3]

My 1970 Chev MHH 90 has hydraulic clutch linkage. The MH 9500 GMC had mechanical linkage in 1973.

2 early types or styles of 2 3/8" guages , till last year or so of Brigadier production size., then they used universal 2 1/8th

Ran the numbers on mine tonight and they are both 75's. Both of mine are 70' s series both are 6v53's both are manual clutches and both have the same dash ...two small on the left four small on the right... The yellow and black one on you tube is advertised as a 66 but seeing as it is a Chevy it must be mislabled. It appears to have 4 holes on each side ......And in onebrochure I have seen a 9500 with what spears to be three different size gauges.
Also the whole manual shutdown thing seems weird to me....my "J" has the manual shutdown but the H has it electric with the key switch.

Woof----Where'd you find the data to cross reference the vin # to a year . I've seen a parts manual that had a little clue, but nothing regular year after year .
