Tori,
today you have plenty of options that did not exist just a few years ago....
For OE stock appearing....
send the drive unit to Jason B. (
@turbo nasty). it will be disassembled, cleaned, new bushings installed, better roll pin to retain gear, and unit is balanced. The cam sensor gear is readily available , if needed - it's just a Buick 350 MSD distributor gear - TA Performance part # 1402A $45.
many other shops rebuild the OE Magnavox drive units - Bison, Steve V, Richard Clark, Don Cruz, etc. Jason B. and Mr. Clark teamed up years ago to begin servicing the drive units.
For OE Magnavox cam sensor caps...
@Thumper (Bill T.) here probably has some left from his earlier for sale postings here and the f*book groups.
I, too, have plenty of new Magnavox caps as well.
The Casper's cap with the LED will work fine when used with an ECM and chip setup to run the engine. The LED cap is problematic when used with aftermarket engine control units. Casper's reviews that info in the product literature for the cap. Casper's cap is best purchased direct from Casper's rather than marked up via on-line vendor stores.
Redesigned Cam Sensors...
Our small turbo Buick group is very fortunate to have innovators like Don Cruz. What he has put together is a really nice piece. His headers are really well fabbed as well.
GBGN1 (Brian P.) FS thread linked in Similar Threads header below had a few cam sensors by Mad Racing Products.
Plenty of turbo buick owners have hoarded cam sensors as there was no alternative for many, many years once the supply of NOS dried up in 2011 and 2012. Now that bushings have been sourced and folks even making new feet for the drive unit body - a lot can be serviced so no need to hoard 5, 10, or 50 cam sensors for just spares. Check the FS section and similar threads from last Fall. many folks listing just serviced cam sensors from Jason and some NOS cam sensors that are not $800 seem to be still available.
