This a fender tag from fellow members ’80 Road Runner. The VIN reads: HL29 G
AB ______.
The “A” is the year code adapted from new VINs as an ’80 Model – but ALL of Chrysler VINs were still 13-digits long in 1980 – even though the industry was to make the change in 1980 to the 17-digit long VIN.
’81 (and newer) Chrysler VINs are 17-digits long.
1979 & older use standard Mopar vin.. 1980 & later use new usdot 17 character vin...
You are mostly correct, but for whatever reason, Chrysler was late to the game.
79 were 11.75" brakes only up front.
for '75-79 B and '79-81 R-bodies.
A minor note: some of the ’75-81 B/R-bodies used the pin-type caliper and others used the slider-type brake caliper. The slider-type caliper bracket will use the FMJ brake caliper and hose without any issue. Just remove the two ½” retainer bolts and slide caliper up and off. Keep caliper suspended so caliper doesn’t hang on its hose (very hard on the hose). Change brackets/rotors, and then reattach the two ½” retainer bolts/retainers and that job is done.
The pin-type calipers are a little different story. You will also need to purchase a pair of brake calipers as well as bleed the brake system afterwards. Still doable but a tad more expensive and longer to perform the change.
There is no rhyme or reason as to which type calipers B and R-bodies received (pin or slider style) – but my experience shows the newer cars came mostly with slider-style calipers.
Slider-style
Pin-style
