I’m doing a nv4500 swap on my blazer and I’m looking for a clutch pedal assembly and I’m not sure where to get one, or if anyone has one for sale I’d be interested in buying it thanks
 
Just had a brief look on eBay and didn't see any hydro clutch assemblies available for sale there. Also checked in our classifieds here and didn't see any actively for sale either. You can always try your local FB marketplace or on Craigslist as well as post a wanted ad in our classifieds and see what pops up.
 
Check with @Capt Ron, he usually grabs them when he can. You are looking for 85 and later squares, they are the ones with hydraulic clutches. Be prepared to spend a bit, its a rare piece. I think I paid around $300 for mine, I could only find 1 in the country when I did my swap.
 
For the last three sets I've sold, I didnt even have to list them.
Good luck.
 
i caan tell you 85-87-91 square body hydro pedal stuff works just fine with 88-94 style gmt400 pass side external slave hydro bell housing swap . you just need to cut and flare a nut on the hard line from the 88-94 and use a union fitting for the metric bubble flare and bleed the system . a blazer i built for a guy i did this and no problems .

note 88-94 gmt400 pass side hydro bell slave needs around 4" lift to clear the front driveshaft on our pass side drop t-case trucks .
 
I can confirm the 85-91 square body clutch master also works with the newer internal slave cylinders in the NV3500/NV4500 transmissions as well.

I used a Swagelok tube fitting to connect the metal tubing off the stock 85 clutch hose to the plastic tubing of the clutch internal slave. I never had any problems with leakage. Expensive fittings but they do not loosen with vibration and have zero leakage up to over 10,000 PSI. I have witnessed them hold onto tubing without any leakage until the stainless steel tubing burst at 35,000 PSI and be vibrated violently for years without coming loose.

The tubing sizes are not the same, so you'll need to order a reducing union of the proper sizes ( 1/4" to 3/16" iirc)
