hi
does 1996 trans am caliper fit on a 89 "Iroc-Z" Caliper Bracket Backing Plates

 

If the 89 has PBR's, yes.

JamesC

 

that would be the rear backing plates, they wont fit the fronts.

 

yes rear backing plates

not sure what update on front I will do

 

89-97 are virtually the same, so there's no real benefit (if that's your intention).

JamesC

 

well James I have drums and my trans am is 84

 

Ah. There's some info at the end of the following link that you might find useful:

JamesC

 

damn did 10 bolt come in 86 I sure that I have 9 bolt BW

 

just count the coverbolts, you never know what ended up in the car after 20+ years

 

or how your memory is bad after only 10 years and mind looks to be real bad . be for I put wheels back under I will do a recount







my brother put the count at 10 bolt and now I need to open see if it is the same 4.11.1 axle and differentials that my brother put in it 10 years ago

and get the number from the cove box to what this Trans am came with

 

The 9-bolt has a rubber plug in the diff cover.

JamesC

 

and the ercount is in 10 bolts

dose this mean that iron-z Bracket Backing Plates will not work?

It will be fun if Ed answers his pm

I´m typing in service parts identication numbers

 

The 9- and 10-bolt backing plates for PBR calipers have different bolt patterns.

JamesC

 

so I need this from Ed

 

i have a 9 bolt, do the F body PBRs also hook up w/ the 3rd gen parking brake cables? I could swear the parking brake stuff is different on the later ones. I think i need 89-92 stuff for mine, including the backing plate since mine has the iron calipers and one side is leading, the other trailing (which looks ridiculous)

 

if I´m not wrong the Chevrolet Astro Van 4.11.1 has 33-spline axles is it Strong enough? for 350 rwhp

 

Yes, and the '89-97 calipers and rotors, etc. I'll be catching up on PMs this evening.

Ed

 

Yes, you need first design rear cables for your '87 and it's a bolt on deal. The leading/trailing thing allowed GM to use the same caliper on either side, lowering cost...and looking terrible.

Ed

 

Ed, are those brake hard line brackets in your new kit?

 

What are 1st design rear cables? What year did they come on? I assume 88-92 w/ the pbr rear calipers?

 

Astro Van will mean leaf springs & no panhard bar, so a LOT of work fitting one in, regardless of the outcome. Might as well get a Ford 9" at that point, then your strength worries are pretty much over with.

 

ok heres one, will a 89 9bolt disc brake caliper fit a 98+ caliper bracket?
