Guess I will let a little info go.
I was doing some research for someone who needed rear parking brake shoes for disc brakes and found some great info. This applies to 89-93 Gbody. 90-93 Abody, 90-93 Cbody, 89-94 Jbody, 89-94 Pbody with rear disc. Some models may be only with the larger rear disc brakes though such as R/t's Gtc's etc.
Chrysler discontinued the orgional style parking brake shoes pn 4383545. They want you to get pn's 4509505 shoes, (2)4509503 adjuster screw, (2)4383539 nut, and (2)4509504 sockets. All for a cool price of $163.00. What it does is retrofit the new shoes to fit. Through doing a little research I found that these new shoes are also used on 93-01 LH, 02-06 JR, 95-00 JA, 95-01 PL, 96-00 JX, 01-06 PT. I'm not breaking down body codes, if you dont know go to allpar. What this means is possibly you could get them at the junkyard if you grab the hardware too. Also I suppose upgrades could be gotten from these vehicles too, although I have not tried any of this. Also there is an economy parking brake shoe available from mopar pn V2013036 for $54.00 and also parking brake hardware kits pn's BHKP7300 rt side and BHKP7301 lt side which are $29.35 each. This brings the total down to $112.70. If you are in good with you parts guy I'm sure you will get an even better price. I ordered all these numbers and all the adjusters are in the hardware kits, I verified it. Also there is NO difference in the econo and OE pn shoes. I ordered those also and pulled them out of the boxes, guess what? Same exact shoes, same exact stamping #'s too, just different boxes, also same exact warrantys too. 12mo, 12K miles. I suppose theses could be gotten aftermarket too if you want but you need the adjuster kits also so why not just order all from the dealer? I thought this may help someone.
