Customers are generally pleased with the drum to disc conversion kit, stating that it bolts up perfectly with minor adjustments and fits well. The booster is praised for replacing less available units. However, some users noted that additional parts may be needed for certain installations, particularly a "slug extension". Overall, the product is appreciated for its practicality and quality, with several users mentioning they would buy the kit again. The product is deemed reliable and effective, outperforming competitive brands in terms of fitting and functionality. Its size is well-received, described as a reasonable and ‘nice’ unit.

Several yrs ago I bought a drum to disc conversion kit for My 63 Belair. The booster went bad and I purchased another, some minor adjustments and bolted up perfectly. Very happy with it.

Part page mentions the need to adjust the pushrod. Total adjustment is only about 1/4 inch. However, the piston in my 67 C10 master cylinder is recessed 1 3/8 inches. Of course, that won't work. A call to the tech help line revealed that I needed an additional "slug extension" to make up the difference. It would have been nice to have a caveat warning on the part page that some installations would need that extra part. Thanks to Kevin for hooking me up with that slug.

Works well for being a reasonably small diameter
